Steps to reproduce: Be a conjurer, use any magic and try to get synergies
I’m unsure if this is specific to Fire magic, because that’s the only conjurer I have.
Pictures/Videos:
The first video depicts me fighting an npc. Fire magic synergizes with it’s own burn effect, dealing 5% more damage depicted by a + sign before the damage number. This doesn’t happen on infused weapons.
The second clip shows that infused weapons are still affected by negative damage synergies, the example being Fire against soaked targets.
