Some other spelling errors and suggestions:
-Stormcharged Axe: a little error in the spelling: "...had to retreated..." ---> had to retreat
Thanks! I'll correct that.
the save vs. spells at the 'silence' effect should have a modifier of -4 instead of -5, and have a duration of 30 seconds. It is enough, not to mention that each attack from this blade can do this effect (95%)
This ability is based on the lvl2 cleric spell Silence and thus the save is at -5 but the effect's duration could be a bit shortened. I'll consider it.
The poison effect should have a duration of 6 seconds (as it is in the description, instead it lasts 10 seconds). This is vital, because 6 seconds is one round and so it has little chance of disrupting the any spell cast in the next round, but the 10 sec. duration will disrupt the next casting very often. Better reduce it to 6 or 5 seconds.
Damn, I wonder how I missed that one? Anyway, it will be fixed in the next revision.
The saving throw vs. the finger of Death effect should be a save vs. death (-2), not save vs. spells.
Not really, since the actual Finger of Death spell requires a save vs. spells at -2 both in BG2 and PnP AD&D (check the spell description).
The Rogue's Cowl is usable by Monks
Not intended, it will be fixed.
