Reset Cooldown + Chaos Troubles

1) Way to reset cooldown for a single item without using dummy items?

2) For buffs that mess up chaos, is the best way to just drop all the items and remove buffs and pick them up after? Will items show on the ground? What would be the best way to do this?

1) dont think its possible.
2) remove all bonuses from the unit, wait .01 sec, add chaos, wait .01 sec, add the bonuses.

Is the wait really neccesary?

what do you mean by remove all bonuses?, what trigger? buff removal or what? because i dont think armour bonus on item is a buff

If it was'nt, then i would'nt put it in the explanation

EDIT :
that would be ur method, like removing buffs/recasting the spell or removing items/adding them back, i suggest u use bonusmod, it saves u the time of having to do all this, but u must trigger all ur buff spells and item effects.

where is bonus mod and if i have to use dummy items for cooldown how would i do so

2. there's no effective way to reset an item's cooldown even with dummy items, u can replace the original item with the dummy, but if u replace it again, the cooldown of the original item is still there (u would do that to allow the item to have cooldown again), so no way to reset item cooldown without using two different units.
