I'm 44 now, and I know i can benefit from Clarity II given by chanters. What other mind buffs (either wisdom enhancers, or just straight mana regen) can I recieve and from what class? And what HP buffs could I benefit from and what classes do I ask for them? Does anyone cast spell haste other then cleric? what other types of buffs do I want/need?

Temperance is probably still your best bet for a HP buff (cleric)

Chanters have other mind buffs that boost mana and wis/int but you will need to check on which exactly.

Spell haste is only clerics.

At 45, you can get a C3 from chanters and Aegolism from Clerics. C3 is all 3 chanter buffs rolled into one, mana regen/wis&int/mana pool.

At 46, you can get C4/5 from chanters and Virtue from clerics.

I am not sure but when you get to around there it may or maynot be more beneficial to get a symbol/skin, for a druid. Virtue definitely has a longer duration, but PotC at 45 and Pot9 at 46 (symbol of kazad is the one that would go with Pot9)

If you can get shaman buffs at any level is a nice boost to hp/ac but for the most part, a chanter and a cleric are the buffers your looking for.

Don't Beastlords also have a stackable hp/mana regen spell line? I'm pretty sure they do, though I have no idea of names, or how long they last. Just came back from 19 months off, and my computer died, so there went 10 days of my 21 free days :(

Ask for 'Spiritual' line - that should get you whatever BST buff you're able to have, though I'm not sure what level you have to be for the lowest one.

beasts give "spiritual dominion", which you can get at 45 (i think) AND "spiritual assendance" which you can get at 61.
POTC you can get at 41 (i think), which gives few hundred HP, and 6 mana per tick (not sure if itas 6). POT9 you can get at 45 or 46, gives more HP and mana regen than POTC.
