From the Grave Trophy in Paladins: Champions of the Realm
From the Grave
Kill an enemy champion after they had already killed you.
How to unlock From the Grave
This will probably be one of the first trophies you will earn in-game. Killing an enemy after they had killed you tends to happen fairly regularly. Especially in regards to using ultimate abilities on point like Skye's bomb ability.
The best characters for this are again anyone with a grenade ability so Tyra & Viktor. Running directly into a point that is occupied by enemies, firing a few shots and then throwing a grenade will damage an enemy that is moderately low on health in turn killing them. Hopefully whilst running into the point you will also get damaged by the champions capturing, leaving you low on health and hopefully causing death.
The trophy will pop directly after you have fulfilled the requirements above in-game.
