1 trinkets that boost your drops:
-rarity: gives a 25 % increase of rarity drops
-materials: give a 25% increase in materials drops
-crown: gives a 25% increase in crown drops
-heat: is not needed since we have the boosters
2 prestige rewards
-danger mission: 1-3 sparks/5-10radiants/elite-eternal orb of alchemy
-normal mission: 1spark/5 shinning-radiants/1adavnced-elite orb of alchemy
-suply mission:depending on the kind of mission either crystals or orbs 3*/5*
That trinket increase is a big no. At least at those numbers. If anything, it should be a small 5% or a maximum of 10% per trinket. Having 50% more profit from any mission is odd.
Alternatively, have them scale per difficulty, so normal gets a 25% boost, advanced gets 12.5% boost, elite gets 6.25% boost. Makes normal more rewarding, but still makes elite a better choice because you get higher crowns, materials, heat, AND rarities.
For prestige rewards, have them depend on your rank. Rank 10-1 and up get 9 radiants + 1 spark from a danger mission, 3 radiants from a prestige one, and 30 radiants + 3 sparks + 1 eternal orb from a supply delivery/gear donation (3 radiants and no sparks for geological surveys and monstrous research).
For lower ranks, have the non-spark items reflect their rank level, such as ranks (7? + )8 + 9 get 4*, under them get 3*, etc.
