Spells consuming more mana than indicated
 

It would appear as if spells are consuming more mana than numerically indicated by the inventory window...
I also noticed that this occurs differently with spells that use more/less mana in that it seems to use on average ~10-30 points more then the spell indicates, any thoughts on this?

Ya its been that way forever... thats why when you hit OOM and then med back up just enough to cast a spell you actually need like 110% of what it says or it will bug fizzle.. meaning you dont actually fizzle in the log, but you lose like 5% of what mana you have and have to med again to get back to where you were.

Pretty sure Succor and Egress use up more mana than it says in the spellbook. Gotta review that soon.

Succor now seems to be wiping out your mana bar nearly entirely. Not only the mana of the caster, but others in the group as well.

As a bard grouped with a druid, I lost 60% of my mana when the druid succored.
