Recommended skill upgrade sequence for "Fire at Zombies"
Upgrade sequence one:
Thermobaric bomb upgrade sequence, super cannonball level 14 (Don’t upgrade once the upgrade comes with a stun effect), in the battle: Continuous Fire > Explosion (Explosion Damage > Explosion Range) > Split > Split Explosion > Skill Attack (The penetration of thermobaric bombs in the early stage is very important , put a penetrating gem (if any))
##Skill gem quality: Core skills>Attack>Current skill damage>General skill damage>First five waves Damage > High HP Damage > Upgraded HP Recovery = Defense Line Damage Reduction > Reduce Cooling Time (may be useful in the later stage) > Critical Hit Rate > Explosive Damage (obsolete skills are defense lines that can avoid damage after a few hits, which are not the current main skills) Gems)
Physical strength is a vital prop. It is most cost-effective to spend resources while waiting for node levels. The next 20 levels are guaranteed to get stuck and require core skill stones.

Secondly, the Cyclone Cannon can also be used, or the jump electron triggers the increase of the electric system, etc. There is no standard answer for which one is stronger.

Upgrade it to one level at most.
As for the skills on the field: if there are only three skills that have risen, it will be fine (Level 6 Hail Generator, Full Level Olympiad Bomb, Level 4 High-energy Ray), don’t Scattered upgrades actually reduce customs clearance efficiency.
Fuel Bomb: After upgrading, the additional damage to monsters hit is really good (especially for ice monsters, and it also has a burning effect), combined with the hail generator's large-area damage and control, At this time, if there is very little gun penetration, it will be really satisfying to upgrade it to increase gun penetration.
The effect of gems also depends on the quality. If the quality is not good, some levels can sacrifice a little output for defense. Upgrading the city wall must have at least 6-10 recovery points, otherwise you will encounter monsters with long-range attacks. , can only watch helplessly as the defense line is quickly destroyed. You must know that distant water cannot save nearby fire.
