Trumna GUIDE

Understand Trumna

Useful when…

  • Consider the listed Auto attack properties separately from the Auto AoE entry.
  • Keep the grenade impact and bouncing AoE properties distinct when considering the secondary fire.

Automatic entries

The Auto attack is hitscan with 29 Impact and 53 Heat damage, listed attack speed 4.67, 24% critical chance, 2.2× critical multiplier, and 30% status chance. The separate Auto AoE entry lists 50 Heat damage and 15% reduction at a 1.6 m falloff endpoint, with the same listed critical and status values. The magazine holds 200 rounds and reload takes five seconds.

Grenade entries

Grenade Impact lists 100 Impact damage, attack speed 1.33, 38% critical chance, 2.4× critical multiplier, and 50% status chance. Grenade Bounce AoE is a separate entry listing 1,000 Heat damage, the same critical and status values, and a 40% reduction at a 6 m falloff endpoint. The weapon description says secondary fire launches an arcing projectile that ricochets off surfaces and enemies, exploding on every impact. The two damage entries do not establish guaranteed combined damage on one target.

Other rifle descriptions

Aeolak and Alternox are described as rifles with two fire modes, and Enkaus has a stated effect on inked enemies at low health. These descriptions establish those stated modes or conditions, but not broader handling comparisons.

Limitations and tradeoffs

  • The 200-round magazine is paired with a five-second reload.
  • Automatic and grenade properties are listed in separate attack entries.
  • The grenade's AoE entry has a listed 40% reduction at a 6 m falloff endpoint.

Common mistakes to avoid

  • Calling the listed attack speed 4.67 shots per second.
  • Assuming the Auto AoE entry occurs with every primary shot.
  • Combining grenade impact and AoE damage as guaranteed damage on one target.
