Enchanter vs Lethality Senna
As we all know, Senna has gotten a few changes recently whose point is to make her viable as enchanter. Her Q heal AP and bonus AD ratio got increased, while lethality scaling on heal got removed. Her passive now gives her 8% crit per 20 souls instead of 10%, and her attack speed growth has been adjusted from 4% to 2%. She is still viable as a lethality support but also got a new build which I'd like to share. What's been working for me is as follows: -1st item: Echoes of Helia (I think it's the best rush for her since her early game as enchanter is lacking, but this item gives her loads of heals and also some damage.); Some people like Imperial Mandate rush , but I think Echoes of Helia is better since it also gives you more healing and isn't as dependant on ally attacking the same target as you. -2nd item: Moonstone Renewer (Currently, that's the highest winrate 2nd item built on her.) ; Ardent Censer/Staff of Flowing Water is also viable (based on who she's playing with, ad/ap) -3rd item: Dawncore (it provides her with lots of AP and heal and shield power, and is contributing to heals, shield, and also damage from ultimate) -4th item: Whatever of the aftermentioned items you didn't buy are viable for 4th item, also you can buy Rabadon's Deathcap for extra AP or maybe Zhonya's Hourglass for survivability. Also Redemption, Mikael's Blessing can be good options. Runes for enchanter would be Summon aery, Manaflow band, transendece, gathering storm, with second revitalize and font of life. For second runes you can also take biscuits and cosmic insight or ultimate hunter with something from that tree (zombie ward for example). As I said, lethality Senna is also still viable even tho lethality scaling has been removed from her heal. The build usually consists of Opportunity, Yomuu's Ghostblade/Edge of Night, Rapid Firecanon. However, the item priority can change in any game so it's not strictly in order. Other good items are Mortal reminder, Collector in some cases Eclipse. Full crit build, while viable, isn't always the best case since you're missing lethality then. Combination of both is the best.
