Vome Invocation

Effect and conditions

At maximum rank, each enemy hit by the Tome’s alternate fire grants 4% Ability Strength for 20 seconds, stacking up to 15 times. At the cap, the listed per-stack values sum to 60% Ability Strength while the stacks remain active. Rank 0 grants 1% per hit and rank 2 grants 3% per hit, with the same duration and stack cap. The effect depends on enemies hit, not merely firing the alternate fire.

Equipment and build fit

Vome Invocation is a standard Tome mod with Madurai polarity, maximum rank 3, and base drain 10. Its listed effect belongs to alternate fire, so it is most useful when the Tome can hit several enemies and the equipped Warframe benefits from Ability Strength. A single hit gives one stack; reaching the cap requires hitting enough enemies before earlier stacks expire.

Ranking and alternatives

The listed fusion steps cost 30, 60, and 120 Endo, plus 1,449, 2,898, and 5,796 Credits respectively. Ranking raises the Strength per hit from 1% to 4%, making it a meaningful upgrade if you can reliably land multi-target alternate fire. Other Invocation mods offer different benefits: Netra grants Ability Efficiency, Ris grants Ability Duration, and Xata grants Energy regeneration. They have distinct effects, so choose according to the resource or ability stat you need rather than assuming one is a direct replacement.

Acquisition and common pitfalls

The listed source is Munio on Deimos, Defense rotation C, with a 5% chance. Do not count on a full Strength bonus from a shot that hits only one enemy, and remember that the effect lasts 20 seconds rather than being permanent.

Limitations and tradeoffs

• Consumes a standard Tome slot and has base drain 10.
• Its value falls when alternate fire hits few enemies or the temporary stacks are not useful to the current ability setup.
