Key Attacks

Underwater Charge : The Abyssal Lagiacrus throws itself towards the hunter in a torpedo like fashion.

Thunderbolt : The Abyssal Lagiacrus arcs its head and then spits a thunderbolt straight forward.

Electric Discharge : The Abyssal Lagiacrus vibrate and its back crackles, followed by a proximity electrical explosion that affects anyone close to it (only occurs when spines are glowing strongly).

Electric Pop : Similar to Electric Discharge, however the attack causes electrical ‘pops’ within the proximity of the Abyssal Lagiacrus (only occurs when spines are glowing strongly).

Tail Flick : When underwater the Abyssal Lagiacrus pulls its body up and then ‘swats’ the space in front of it with tis tail.

Whirlpool : The Abyssal Lagiacrus creates underwater whirlpools to try and disorient hunters.

Recommended Strategy

Perfect your underwater Lagiacrus fighting. Yup. The Abyssal Lagi’s electric attacks are more devastating, so you’re recommended to attack less and dodge more.

Also, you can use the Ballista cannons in this fight as you did against the Ceadeus, so make good use of their firepower early on. When the Abyssal Lagi enrages, move around and move quickly - let it calm down before considering attacking again.
