Overview
Obsidia is a marksman (MM) that that you use in gold lane you just need to stack her passive to maximize you're damage throughout the game.
Strengths
When Obsidia use her ultimate any one who get target can't use their dash skill (only work on one hero) so Obsidia is a good counter to some exp heroes like Alucard because Alucard can't use his passive.
Weaknesses
Obsidia weakness is when she is ambush by ang hero with burst skill like saber or Eudora

I use inspire because inspire can increase attack speed which can maximize Obsidia damage (but still you need to stack her passive throughout the game)

Best With Diggie
100% co-op win rate
Diggie is the best bodyguard not only it can protect you from CC or stun it can also check bush with the use of there first skill to know if someone is hiding in the bush.
Watch Out For Miya
100% counter win rate
Miya can cancel Obsidia ultimate but depending on the skill cool down if the one or other heroes can't use their ultimate for the meantime because of cool down the other will be defeated (but it's entirely depends on the user).
