Understand Sey-Taph
Useful when…
- Use when frequent Void Sling movement makes its resource cost a concern.
- Consider another Antique when you need longer sling distance, Void Mode benefits, or container breaking instead.
What does it do?
Sey-Taph grants +5% Void Sling Efficiency at rank 0, +20% at rank 3, and +30% at rank 5. Its effect is specifically for Void Sling efficiency; the provided details do not define how that percentage translates into a particular amount saved per use.
When should you equip it?
It is most relevant when Void Sling is a regular part of your movement and you want its uses to be more efficient. For distance, Esti Vel-Ikha instead lists +30% maximum Void Sling distance and a radius bonus tied to Mods from unique Schools. Kaal-zidi affects Void Mode efficiency and conditionally adds movement speed based on Naramon School Mods. Lashta-Vak gives Void Sling a container-breaking pulse, with range scaling from Mods from unique Schools. These have different effects and conditions; none is a direct replacement for efficiency.
How much should you rank it?
The mod has a universal polarity, starts at zero drain, and can be fused to rank 5. Its listed effect rises from +5% at rank 0 to +30% at rank 5. Rank it according to how much you value the efficiency gain against the Endo and Credits needed for fusion; the provided cost examples show increasing costs at higher ranks.
Limitations and tradeoffs
- Uses a mod slot for a Void Sling-specific efficiency bonus.
- Higher ranks improve the listed percentage but require additional fusion resources.
Common mistakes to avoid
- Do not treat Void Sling efficiency as Void Mode efficiency; the listed effects belong to different abilities.
- Do not expect Sey-Taph to increase sling distance or break containers.
