So I was testing out unduped piggy and sig40 void (both r1 atm), to decide on my next r3.
I was trying them out on the AoA gauntlet to see how they performed. Both managed to take ~10% off of tigra before dying. Then I looked over to the right, f*** it let's try them against jabari. It's not a favourable matchup for any science champ tbh, but I had time to kill so why not?
To my surprise, I guess I wasn't familiar with void's game, he almost managed to solo that jabari fight as an unboosted r1 science champ. First attempt too.

Kinda wild. I had a hard time with that fight even when I was using my r3 sinister and r5 ascended onslaught.
I'm pretty sure he fits 3 objectives (villain + saga + science/mystic/cosmic), so he could be a decent option.
For this fight: Just spam sp1s, while trying to push jabari to sp2s (her sp1 ensnare messes with his debuffs converting to fear of the void passive). Once you have fear and petrifies up, he can reverse her block regen. Willpower healing is huge here to mitigate that block dmg. Jabari also gets heal block and armor break debuffs on her from a node, so it further boosts his dmg.
All that to say, my next r3 has been decided.
