Talk:Luden's Echo/@comment-405747-20150314073937

So I actually tested this item out with (as he has a single-target sustain spell and three AoE spells) and went with his usual  and. As far as I can tell, unlike the bolts proc from, the bolts proc from this item DO proc on-spell cast effect items such as the  slow and spell vamp (I tested this on a group of minions). However, the bolts will be treated as area of effect, so the slow and spell vamp will be applied at reduced effectiveness. That being said, if you are using a single targeted ability on a unit when you expend the charges, the slow and spell vamp will be applied at full effectiveness while the bolts apply the effects in a reduced effectiveness.

Oh yeah, Vlad's single targeted self-heal is not applied three additional times from the bolts. So I'm assuming that Luden's Echo bolts do not apply on-spell effects from champion abilities like 's Q or 's Q.
