Overview
She's a hero that fully depends on kills, pushing turrets and clearing minions. Teammates shouldn't steal kills instead they should give her kills.
Strengths
She's a very strong hero in late game yet very weak in early, she can be either strong or weak in mid game depends on the player, if the player got kills and pushed turrets while clearing alot of minions in early-mid game, then he'll have good farming for her and got alot of stacks to boost her damage. In this case she's a strong hero in mid game, but if the player couldn't do that due to his teammates or how the match went then she'll be weak in mid game. Her teammates should give her kills to make sure she keeps getting stacks and boost her damage and strength.
Weaknesses
She fully depends on her stacks and the problem is she can only get them from minions, turrets, hitting or killing enemies, so in this case farming in the jungle mid match won't give her stacks, she can't really change the match from losing to winning in this case, as we know many marksmams can change the entire match and carry their team to win after they farm mid to late game through the jungle getting more gold and exp. However it's not the same with Obsidia, her damage fully depends on her stacks, mid to late game sometimes it's hard to push turrets or get minions if the enemies have a big gold difference and they watch for their turrets while also cutting lanes so your teammates can't get gold from the minions and turrets.

Late Game heroe
Her strength shows in late game or after farming alot for her stacks.
Best With Carmilla
Carmilla can be a good match with Obsidia because of her ultimate and stunning enemies, her ultimate allows Obsidia to deal damage to multiple enemies in the same time instead of one enemy, which is good especially in late game. Other heroes like Khufra can be also good stunning enemies for her so she can kill them and get more stacks.
Watch Out For Gusion
She's very good against heroes who depend on dashes. She can also prevent Hayabusa from using his ultimate when she ults him.
