So I was strategizing for leveling up my alts with armor past 20, and I was looking through the guides and I couldn't find this info anywhere regarding the amount of light in each armor piece with each defense upgrade:
Blue level 20 armor starts at 13 light and can get you to 15 light (no ass shards needed)
legendary armor starts at 18 light, and the first two defense upgrades get you to 22 light (2+2) without ass shards, then three more defense upgrades get you to 27 light with 6 ass shards for each upgrade that give you 1+2+2 light in that order.
Raid legendary armor is the same as legendary armor except for 6+6+6 shards your last three defense upgrades give you 2+3+3 light for a total of 30 light in that order.
Exotic armor starts at 21 light, can go up to 23 light without shards, and the last three defense upgrades require 8+8+8 shards and get you 2+3+3 light in that order for a total of 30 light.
I was interested in this info and I couldn't find it in any guide. Please correct if it is wrong or missing details. Thanks!
