I've got a better beast slayer for weapons last night that would be good for the lower level guys that tend to fight mostly beast at lower levels that you guys might be interested in.
+6 against beast to any weapon. the cost of the material to do it is not bad if you want to give your Alts or even a current character an edge!
The prices change depending on the AH availiblity.
nope you can be any level to recieve any enchant. so you could have a lower level guy buffed to the max if you wanted to spend the money on reagents.
The only drawback is that the equipment that you enchant doesnt keep up with your characters progress. ie you enchant a level 6 dagger but in a couple of days you are up to level 12 thus making the dagger by that time junk.
Im going to wait till my alt is level 12 before I buff him up a bit with some cheap enchants, then when he gets in his 20's he'll be "WeeBit, rogue gnome, killing machine".
