Supply Kit
Supply Kits reduce the cost of missions by 25%, increase Crew XP by 50%, and award Bonus Rewards for completing Away Missions and Space Battles. Supply Kits can be bought with and their effects last for 24 hours.
Chroniton Cost
When players attempt an Away Mission or Space Battle, the cost is reduced by 25%. This is rounded down the nearest integer. At Warp 10 the individual cost is first calculated, then multiplied by 10.
To maximise savings, a player with a Supply Kit active should complete missions with a cost that is a multiple of four, e.g. 4, 8 or 12.
Crew XP
When an Away Mission or Space Battle is completed, the crew used will receive 50% additional XP. However, this is inconsistently calculated and potentially bugged. Presumably it is intended to be 50% of the original XP reward, rounded down the the nearest integer; but sometimes it falls significantly short of 50% or even lands above 50%. This will not be received if the Mission or Battle is completed at Warp speed. Instead the player will receive Bonus Rewards of Federation Training Programs.
No additional Captain XP is awarded.
Bonus Rewards
The awarded after Success on an Away Mission or Space Battle are doubled.
If a player runs a Mission or Battle at Warp speed, they will receive Federation Training Programs as Bonus Rewards instead of the Bonus XP they would have normally received.
