the cooldown of emitter sentry’s debuff after inflicting the debuff
the type of bombs that the grenade sentry yeets after tech upgrade
how much repair does repair sentry gives to a sentry
the range and damage of the two ranged sentries
(i noticed that minigun sentry’s bullet change in t3, so does the sentry can upgrade to venom bullet or some bullet in some upgrade, i always not able to get the sentries to more than t10)
does the tank sentry gets damage reduction?
