Arc Coil GUIDE

Understand Arc Coil

Useful when…

  • Equip it on Diriga to zap nearby enemies.
  • Raise its rank to increase the number of enemies affected per zap.

Range and effect

Arc Coil is a standard Diriga precept with Penjaga polarity and base drain 2. It deals 100 Electricity damage per affected enemy with a 10% Status Chance, targeting enemies within 10 metres.

Rank changes

At rank 0 it can zap up to 2 enemies; at rank 3, up to 5; and at rank 5, up to 7. Damage and status chance remain listed as 100 Electricity damage and 10% across those rank examples. The rank 4 to 5 example costs 160 Endo and 7,728 Credits.

Choose by Sentinel role

Electro Pulse instead continually zaps one enemy within 15 metres every 5 seconds and traps that enemy in a stunned state. Calculated Shot charges a powerful shot at the first enemy within 70 metres. These Diriga precepts offer crowd zapping, periodic stun, and a long-range shot respectively; select according to the effect you want.

Limitations and tradeoffs

  • Its 10-metre range is shorter than the listed ranges for the comparison precepts.
  • Rank raises the maximum number of targets, not the listed damage or status chance.

Common mistakes to avoid

  • Do not mistake the 10% Status Chance for a rank-scaling value; the supplied rank effects keep it constant.
  • Do not expect it to target enemies beyond its 10-metre range.
