IIRC they are:
Health: heal 1 HP per pact level per turn when under 10*base BOD
Strength: +4 damage to 'unarmed' combat
Haste: speeds up crossing maps in freemove mod (not to be confused with the bug which happens shortly after map load)
Gaes: restores point to Magic attribute of PC.

Money gets you the change under the couch.
Peace zeros the heat.

people have complained that haste is not cost effective.

Hmm, Health and strength seem like the most effective, unless you decide to go from cyber to magic...Money is just about worthless, I did it on my first character and it was only worth 10k. That's two big runs from Frosty.

Thank you for answering me, though. :)

Money: 10,000Y per pact
Health: regenerate 1 hp per time unit, per pact (second? turn?)

I think a time unit is each move or interaction you make, but im not certain..

I used the money to get the Renraku deck on my oh-so-experienced (but oh-so-poor) mage with decking. She had earned a lot of karma but not much cash. I wrote about the issues with that pricing elsewhere.

It's not in any way a balanced trade. 10,000Y is not "wealth" in this economy, I watched an old Lets Play that showed Eric paying out less than 100Y a mission, and prices for items matching the base game economy. There was a message in one of the Youtube comments that Southwind had recently adjusted the economy. So, it's possible that he didn't adjust the payout from Xalthu. At the point that spells, weapons, and programs are each priced at a few hundred nuyen, 10,000 _is_ wealth. It's only couch change in the present economy.

Yeah, it's why I worded it vaguely. My char with the pact doesn't get injured often (high quickness/dodge) so I haven't watched it much.

She did regen after getting clipped by the cab, and her heath came back after 5 ticks.

think of a point of it as a way to regenerate between runs without breaking out the medkits or waltzing back to your safehouse.

This assumes all given stats that you reduce are set at 3 (in other words, the lowest price you can possibly pay).

Money - 10,000 nuyen for 30 karma (no limit)
Effectively, a complete joke. 30 runs from Gunderson to gain the 30 karma will earn you more than 10,000 nuyen. Eachna is most likely right, when the "inflation" occurred so long ago, Southwind simply forgot to adjust this value. Even at 100,000 this would be a hard sell assuming there will eventually be fixers above Frosty.

Regeneration - Heal 1 hp per turn for 60 karma (no limit?)
This also works outside of battle. It can effectively save plenty of time and money as you will no longer need to heal between runs. However, you can also take this boon more than once (making it 2 hp, 3 hp, 4 hp, etc. per turn). In battle, 1 hp per turn is near useless, but enough of this pact stacked could in theory make you invincible. But then, that much karma would make you invincible anyway.

Power - +4 to unarmed damage for 60 karma (only good once?)
If your character's primary damage method is unarmed, then this is THE thing to get. Save up 60 karma ASAP and get this! Otherwise, you can ignore this since it ONLY improves unarmed damage.

Speed - Move faster on the map outside battle for 90 karma (only good once)
Honestly, you might make the argument that it may save you a lot of time thus earning more money/karma eventually. Still... 90 karma just to move faster outside battle? I suppose a future update will include an option to remove the loading screens for 120 karma.

Magic - increase magic attribute by 1 (but not above 6) for 60 karma (limit - 6)
Basically, this allows a magic-based character to install cyberware and still have the best possible magic. I suppose a mage would want to get this eventually, but with all the possible things to spend karma on, it's not really a priority. All characters not using magic can ignore this one.

Peace - Sets Heat and Notoriety to zero for 30 karma (no limit)
I'm not 100% sure how heat works ATM (it's not clear how fast it rises and falls). Seeing as how the price of a Notoriety wipes rises over time, it may be possible that in the future, very high level characters may actually spend absurd amounts to reset it, and 30 karma may actually be the cheaper option! But at the moment, this isn't of much use.

I seem to recall wealth was 3k nuyen back in the old economy... either way, not a particularly effective use of karma.. then again, in my opinion, all these boons are simply meant as a karma sink for those characters with nothing better to do with their karma while they desperately attempt to scratch together enough real wealth to buy an excalibur or high level cyberware! =D ... but let's face it, until all the high level fixers are in place as well, we wont have a particularly good idea of what the overal economy will feel like. That being said, 10k nuyen aint much ;)

@Mizaroth Yeah. 10k is too low. It depends a little on how many karma points it takes to get a pact. I'd think something like 50k would be more reasonable. As others point out (Toad_004 and Weyroc), the cash and missions are linked in peoples thoughts.

Using Eric's payouts are too low. At the point that you have enough Karma to think about selling stats back, you're going to be doing Frosty's missions. 50,000Y is about right if it's really 30 karma per pact.

That gives a bit of warehouse upgrade, or some nice cyberware, or a few spells/programs. Nice, but not "game-breaking".

Thanks for this testing Toad :D. I put the information on my wiki page but edited out the speculation on the nuyen inflation since Mizaroth remembers it being lower in the past.

Xalthu's statement about the kinds of pacts available is: "Wealth. Power. Health. Knowledge. Almost anything you can desire."

I don't see anything in the above list that would be "Knowledge". This is disappointing as I was hoping for a way to trade one batch of Karma and get a lesser amount back. This would, in effect, be a "re-spec" rather than a straight "awesome boost". Southwind might want to allow an option to trade 30 (already spent) Karma for 20 unspent Karma (Xalthu would keep 1/3 for its own needs). To allow some granularity in the trades, you could have a trade 30 pact for 20 karma option and a trade 3 pact for a 2 karma option. (a large trade and a small trade in the option list) and could be classified as a purchase of Knowledge.

That would allow someone who preferred to move some stats around to sell them back and then spend the (lower amount of) new points elsewhere.

Speed is useless (as Toad points out) and is in NO WAY worth 90 Karma. Much more useful would be to spend 90 Karma on an extra AP. This would be a one-time purchase and would stack with all AP gains from Karma spent.

Xalthu also needs an option to sell back blocks of skills.

Right now, you can either sell points from attributes (Strength, Quickness, etc) or points from primary Skills linked to a particular Attribute (Dodge and Ranged Combat are Skills linked to Quickness). However, it didn't take any points from my Pistols when I sold my "Knowledge of Speed" (because that's a specialization).

What would be helpful (and again, useful to someone who wants to respec), would be to be able to sell back Ranged Combat PLUS any Specialization gun skills and get a pool of Karma for it. Then, you could spend the new Karma on (for example) unarmed fighting if you wanted to try out that style. The same with Decking and ESP Control, etc.

It would allow players who prefer to keep the same character and respec to have a valid path through the game.
