Stealth spiderman synergy not working in 6.1.5

BRTIL

I've been trying a path in 6.1.5 I have tried to use the stealth spiderman synergy with imiw to get through the incinerate path: proxima, ultron, hela... however when the opponent was slowed I still died to incinerate

Stark Internship synergy:
•Spider-Man (Stealth Suit): Slowed Opponents also have the Ability Accuracy of Shock and Incinerate effects reduced by 100%.

This means that once the slow is on the enemy, they can't trigger an incinerate on you. It won't cancel any existing incinerate effects on you. If I'm not mistaken, the node places the incinerate debuff on you immediately and will take all your health in 30 seconds. I'm not sure you can stop the node with Stealth Spidey.
