Hello! This aronzei and this is my concept remake of Zac.
I actually made an AD Zac and it was really fun. With aand diving in with , attacking then using the active, made a decent burst. So I thought, "Why not make him change forms along with AD? In fact, why not make him scale with AD?". And this happened.
See when Zac files came out, he was presented with 3 forms - one that grows, one with spikes, and the blob form. See here.
I always thought AD was expected (and will morph him into that clawed creature) but when we all played him, we knew that his builds are limited. For a blob of varying forms, his viable builds is ironically limited to only one. With this idea, it makes him playable as AD, AP and tanky. However this is just a concept (no balancing yet) since I'm not really keen on the numbers. The hidden passive where his size increase is maintained combined with the form altering passive. (eg. High AD makes him color red, look sharper and slimmer. High HP makes him bigger.)
As you can see the icons are just a modified and inverse colored of the original icons just to show an idea. The general is his blobs are replaced with spikes to imply physical damage.
I would be really happy if this was real I'm just happy that somehow I made it tangible how I saw Zac - a versatile champ with multiple forms and builds. With that said, I hope you enjoy this Zac Concept remake.
