You know, your stuff gets ignited when you hits char from his team. Now, I have never bothered killing him first, since he doesn't do much, but I wonder if he is providing the ignition aura to his team, since those mobs normally does not have ignition shield or whatever.

He does. If you kill him you will no longer be ignited when causing TAI damage to archer Zetsus.

The puppets will still ignite even if he'sdead however.

if we look at the current teams, ignition changes nearly nothing we crush them nonetheless. but having deidara attacking would make things more interesting. i just feel like he's useless in there ;P

Hello,

There are some issues known to us with the TI, our team is working on it.
Thank you for your report regardless :)

Have a nice day ^^
