- ?????? (+Defense, +Alacrity) (This is the missing Tier 2 Prefix)
The tier-2 name is also Redoubt.
Redoubt (+Defense, +Alacrity) ** comes from drop recipe blue items with +alacrity
To verify this, buy or otherwise come across a blue item recipe that has stats with Alacrity. I used the blue blaster: lvl 39 Particle Beam Saboteur -> RE -> learned purple recipe "Redoubt Particle Beam Saboteur" (Adds 32 defense, increases tech power by 59, also +26min dmg and +48 max dmg). I haven't RE'd the purple one because I still don't know if legendary quality items are possible through REs.
