Recommended Sentinel Crystal Upgrades
Napalm Belch For Survivability
The Napalm Belch should be prioritized first as it gives ammo and health boosts, both of which are essential during the early levels. The perk, Napalm Belch, increases the length of the on-fire effect on Heavy and Super Heavy demons, making it easier to survive as they give you armor when you damage them.
Quickdraw Belch For More Armor
The reduced cooldown and increased armor & health given by taking the Quickdraw Belch helps in keeping you on your toes during heavy battles. Take them once you have enough Sentinel Crystals to spend.
Go For Belch Armor Boost
The Belch Armor Boost forces demons to drop armor faster and is useful when going against aggressive melee demons. Just use Belch on them and watch as their damage is negated by the armor shards that they drop.
