There are several skills and armor sets which boost the Spell Damage of others in a dungeon. For example, my Sorcerer can boost Spell Damage when he heals players who are already at 100% health while wearing his Spell Power Cure set. (It's a 50% chance for the buff to occur.) My Dragonknight can grant the Major Sorcery buff to give allies 20% extra Spell Damage by using the ability Molten Weapons or one of its morphs. My Templar can grant the Minor Sorcery buff to give allies 5% extra Spell Damage due to his Illuminate passive, which activates by casting any ability in the Dawn's Wrath line.
Many Healers do their best to buff others' Spell and Weapon Damage to improve the group's DPS.
Do I get a spell/weapon-damage-increase-buff, when inside a dungeon with other players?
I have noticed that inside a dungeon after group finder, my spell-damage on the character sheet is substantially higher compared to when i'm exploring around in Tamriel. Is this normal and a courtesy-buff for all players in the dungeon? Is it a bolster like there is in astor?
Thank you for your response.
