Yeah . . you all are judging the item without even SEEING it, having no idea of the level of difficulty of the encounter, having no idea what else is involved, based solely on an instrument mod. That's a little dubious, based on
this thread.
In any event, there are several things I can tell you to consider without disclosing high-end content:
1 - To be useful, the mod on the drum pretty much has to make up a part of the melee dps lost because you can't equip weapons. At that level, a bard is doing ~120 melee dps; and your puppet (or thaz legs) are already doing a perc. mod of 2.0-2.2.
Now I'm not going to sit down and do the math myself, but let me ask you what instrument mod you *think* a percussion instrument should have at that level to increase DoT damage by 720 damage/tick
over a current mod of 2.0.
2 - The drum is at least
three tiers above the previous one available. That will be reflected on the item itself.
Think about it and tell me just how much a drum should increase in modifier every tier, and then tell me what you'd end up with when you get to thaz level from poair trash.
