Can someone break down the mega boss fights?

[Raindustz]

In a very simple way. What should I be doing in each fight? I tried and spider and the blob and I could LIVE for a long while, but I did no damage to them...

you need to mouse over them and see what buffs they have and what thier weakness is.

How do I see what a buff does? I can see the name of a buff but it doesnt show the context of it?

You're looking for their damage resistances. Right-click on the enemy's selection circle to lock the info window, iirc.

I've only done the spider and blob myself. First, are you at level 20? With all your endgame gear, fully upgraded? You probably want to be. Sounds like you're level 20 if you're surviving, but if your weapons aren't maxed out you're probably getting your attacks downgraded a lot, as both have very high defenses and resistances. You'll want any buffs that increase damage, accuracy, and penetration. Beyond that, they're actually mostly puzzle bosses.

Spoilers:

There are probably more efficient ways of doing these, but it's a start.

With Belranga you'll want a very good tank. Eder, most likely. Stand in the lower left and have him guard the bottleneck and focus all your energy on just doing damage, buffing your attacks and debuffing her defenses, and doing what you need to to keep Eder standing. Don't kill the spiderlings as the boss gets a stacking buff for each one that dies, and she'll eventually be able to one-hit Eder. Just focus-fire on her until she dies. She's a little less resistant to Corrode and Crush damage. Use Raw damage if you have it.

For Hauani O Whe, you'll want to be able to interrupt reliably. Every time each blob splits, it has slow charging ability that lets two blobs merge back into the next largest size at full health, and you definitely need to stop that from happening. The crossbow modal works well for this. If you don't have many interrupts, you can retrain a monk or hire a new one just for this fight.

Other than that, the blobs are very slow and telegraph their biggest hits, so if you're not having any trouble staying alive, you should be fine. The blobs are pretty much immune to mind/fear effects, but their defenses go down as they get smaller, and they're somewhat vulnerable to elemental damage.

I just killed Belranga few minutes ago. The trick was for me to actually kill all the spiderlings (don't touch the burrows) because she get -1 to all resistances for each spider killed. So after like 80 I could start hitting her and killed her eventually. At some point (100+) even the spiderlings themselves hurt her because of their AoE and her low fortitude.

I used summons (figurines and tekehu's spell Watery Double) that stayed close to boss so she hit them while I killed the spiderlings.
In any case don't get close to her because she has an ability that chew her target, prone him and giving him an injury so just use summons to tank.

Also you probably noticed her paralyze so rest with Shark Soup to get immunity. Bring a lot of scrolls too for the long fight. I also used the cipher spell Ancestor's Memory on my spell users to replenish their spells.

Good luck!
