Some ideas (need a little tinkering obviously - and really as much for names and grades ie: cold, frost, ice ):
http://shrines.rpgclassics.com/pc/mm7/enchantment.shtmlhttp://classic.battle.net/diablo2exp/it ... /suf.shtmlhttp://classic.battle.net/diablo2exp/it ... /pre.shtmlPrefix/Suffix can stack, if they do the same thing.
Might be best to stick with one of each (names could get a bit silly, although you could make a oprefix/suffix that has more than one effect),
'ix's with a positive and a negative.
Heavy Handed: +AD - attack AGL
Heavy/Dwarven: +AD/AC -stamina regen
Light/Elven: -AD/AC + stamina regen
demonic: high AC/AD but drains health each tick or stops regen.
Things that have a chance of doing something when you are hit (small healing on wearer who is hit, small damage on the person who is hitting the wearer, debuff on person hitting wearer, buff on wearer getting hit).
Things that have a chance of doing something when you hit something (as above but in reverse).
Vampiric: Drain (some) health of enemy being hit (for weapons, think leech spell, but maybe for less healing or chance based).
Mana/Health regen (already mentioned).
Toughness: +AC
Sharpness: +AD
Shielding: Provides a small "shield" effect, damage comes off this first, it regens each tick.
Elemental Damage/Protection (mentioned already).
Crystal: High +to AD/AC but has a chance of breaking (maybe just weapon and it will break on first hit, but does high damage?).
Invisibility: Can cast fade once/twice/thrice per set time period (actually, items that mimic spells).
Re-animation: has the chance of raising something it kills as a pet (only one pet at a time?).
Confusion/Conversion (only works on mobs) has the chance of temporarily making an enemy mob an ally or having it attack randomly
Something that adds 1 stamina (could even offset it with having it slow stamina regen, maybe a lesser one that slow stamina regen and a greater one that has no effect on stamina regen)
DoT effects (already planned eh).
Stunning effect (but just slows stamina regen a little)
Anyway, back to Hellgate London.
