Won't have enough to put on each gun I craft. And gambit memento drop rate is bad so i'm not going to use That. Raids could also get mementos. Examples: Complete raid 50 times to unlock. Go flawless 10 times. Gild conqueror title 5 times. Gild gambit title 2-3 times. Complete dungeon solo flawless. Etc. Just use a shader for the memento themed after activity. Example: Vog-glass shader Duality-like the red Skull ornament Votdisciple-resonant spikes with yellow glow. Prophecy-neon purple Last wish-taken Shattered Throne-hive green with green glow. Grasp of avarice-yellow with engram patterns Etc.
