Overview

• Pros
• Cons

Pros
General Both moves break Instinct. High damage. All moves mostly work extremely well in the air. High combo potential. Both moves have low endlag. Great for grinding. (High damage, decent M1 cooldown, and useful knockback for combo setups.)
Normal Attack (Tap) Highest M1 damage out of every gun. The poison breaks instinct. Good range. Extremely high damage when paired with the burning enchantment. Applies small knockback and brief stun, useful for extending or starting combos.
[Z] Spiky Bomb Medium stun.
[X] Acidic Smoke Good range. High damage.

Cons
General Rubber users are immune. All moves have a slow speed. High mastery requirements, especially for a Gun.
[Z] Spiky Bomb Very small hitbox. Very hard to hit from afar.
[X] Acidic Smoke DoT is rather hard to pull off. Low Stun.

Tips

• It is recommended to use macros to perform one-shot combos easier/faster.
• The Acidum Rifle is mainly used in "skilled builds", best paired with Soul Cane and Superhuman.
• The M1 attack deals slight knockback and stun, which can help reposition enemies for follow-up attacks or combo starters.
• Gun mains use Acidum Rifle frequently due to the powerful M1 and stun(s), especially if paired with Ice, Dark, or Rumble.
• [Z] Spiky Bomb can stun enemies for a short period and allow the user to start combos. In addition, it prevents the annoying knockback on some moves such as Superhuman [C], Death Step [X], Quake [C], etc.
• Use [X] Acidic Smoke to break Instinct and then follow up with a stun, preferably Soul Cane Z if the player is a gun main, and then use their combo.

Trivia

• The Acidum Rifle is widely used in PvP due to its ability to break Instinct, have large AoE stun moves, and extremely high damage.
• When equipping this gun, backflip animations when jumping and dashing will not show, although the user is still able to use them.
• There may be visual glitches when the Acidum Rifle appears in front of the player's character. This is due to the avatar's arms, and the player will need to change their avatar's arms to fix it.
• Acidum Rifle is the only gun that goes around to any players back.
• Many players in the community, especially skilled ones, complain about the rework making the Acidum Rifle's moves harder to hit. Although it was "fixed", it is still arguably worse than pre-rework due to the moves' animations seems to be smaller and not as "destructive" as pre-rework.
