any of the paid stuff worth getting?

[DeadJericho]

i dont even know what some of it does
eg. Haskel - what is that? a new minion to send on quests??

Haskel is a character you can select after purchase. It has no extra abilities and no advantages. It is essentially just a cosmetic.

As for the other stuff. Avoid the time limited boosts, they are not worth it at all. You should get the permanent soul upgrades though. The material bag max amount and drop rate upgrades, as well as the CPS upgrades, are nice to have (in that order).

But in my opinion none of the items are worth the asking price, too expensive for too little gain. Just wait until you unlock daily quests to get eggs. The eggs can drop jewels and after a while you will have enough to buy some of the more useful upgrades.

Never buy temp bonus's, ever.
Only spend your gems on the permanent upgrades. Prioritise SP bonus's and armory equipment chance like +excellent and options.
Cps is good too, but not as useful as the prior. You will also want the material increases at some point as well. Basically, you will buy out the entire soul tab store just using the gems you earn for free as you play. Just spend it wisely as you slowly work your way through it, and never buy the timed temp bonus's, those are a waste of gems, there's zero reason to whale in this game. You can buy everything eventually.

basically this stuff seems to be there to support the developer a bit, since the game itself is free and a one-man project like this is really timeconsuming.

I initially played the game as a trial, to see if i would have fun. I had some fun and thought, now is the time to pay to disable the ads. And i was expecting like 2$ because mobile pricing. 4$ would have been fine. 8$ to just switch off ads in a game that has lots of other monetization and that can just vanish off mobile at any time.

So now i feel guilt free about paying nothing.
