So kino1, PP max targets is 9, cyro3 icewall is 16.
if you make a formation, after it eats up the 9icewalls, as long as you continue holding it down, it will start eating up the 7 left?
No. Level 5 Psychic Pressure range won’t be able to reach the remaining 7.
lv 15 ice wall lasts about the same time as PP. So no need for the 7 left unless someone destroys your walls.
PP lasts 15s, 30 hits (2hits /s)
Icewalls lvl 15 = 16 titles with 32 "hit points"
Besides that, keep in mind PP’s range can reach ~10 titles in normal way.
