Make Annie become Tibbers instead.
NOT ACTUALLY, but make Tibbers his own champion with his own skillset that you control IN PLACE of annie.
WARNING WHAT YOU ARE ABOUT TO READ DESTROYS LORE AND MAKES ANNIE SOMETHING ENTIRELY DIFFERENT.
How this will work, Annie passively follows you around like a minion and autos enemies, (but what if annie dies ?) During your ult the only way to get a kill is if Tibbers himself dies.
What will Tibbers spells be?
Same Passive as Annie. Q - Some sort of swipe attack W - Like a roar, like chogoth but flames instead (so same W effect) E - Sort of a dash, hard to explain, like a sion ult but really short, no knockup, stun if passive is up. R - (active only if Annie Dies) Tibbers goes on a rampage and all his spells damage are doubled and his cooldowns halfed.
Tibbers form could be held up to a minute, Hitting R when Annie is alive would put him away. If annie dies and tibbers is out and the minute ends, Tibbers reverts to annie.
