Picture the earthquake spell for examble (or any AOE knock down spell). You could have the bigbys fist graphic show up, do its open handed down ward slam animation. Except you could have two fists appear and slam the ground as the initiation of the earthquake.
I've already reenvisioned popular low level effects and here is some more visuals:

Mage Armor - The key here is to update the spell without making it look too fantastic and therefore more powerful than it is. I've opted for rotating columns to give the impression of magical defenses at work.

Fireball - Everyone knows magic fire is green. If you don't you need to watch more obscure 80's tv shows. Either way there are way too many stock orange fire explosion vfx in game. It needed a change.

Bull's Strength - pour that sugar on me mr giant fist!
As a more concrete statement on where Islander stands; I am in the final area (3 of 3) of the final dungeon of chapter 2. I have to put in some landscaping and some interactions and one big cutscene and well... it's done. Polish and two optional quests will be added later but it will be a stand alone, playable 2 chapter campaign at that point and the testing calls will begin.
