This guide assumes you are already familiar with the basic mechanics of Kerapac which can be seen here #kerapac-hm-basic and own BIS gear in Magic.
It is highly recommended to have a Nodon dragonkin slayer task 
as the helmet boost does work. You may also use the Premier Artefact 
to have a 10% chance to not decrease the slayer task count with each kill.
These rotations cater to a max mage setup. Due to the randomness of critical strikes affecting your rotation when under 
and the mechanic of 
, it is difficult to have a definitive rotation which means that improvisation will be necessary.
can be used instead of 
as you will not be having any hitchance issues during the fight and it lowers Kerapac's magic level and applies a 1-minute accuracy debuff making it less likely for him to hit you. It also does the same damage and has the same adrenaline cost along with a cheap cost to purchase.
Preset Suggestion & Breakdown
⬥ Magic
Additional Considerations/Info
⬥ An 
can be used alongside an 
for phases 1 through 3, switching to only for special attacks and for phase 4. This should be around a 1% damage increase in exchange for extra effort.
• Ensure you use the Leech Magic and Leech Magic Strength curses when using until P4, where you switch to 
⬥ 
may also be used in exchange for an inventory slot and time gathering them although be wary when using them on echoes as they can sometimes run too far thus making them disappear, they will also continue attacking echoes even after death disallowing you to use another until you move far enough away.
⬥ Headhunter's thrill bracelets may be used as a switch to prolong slayer tasks. The Trophy-Taker's perk also does the same.
⬥ IMPORTANT: The following rotations have not been updated to account for changes on 5 June 2023.
Overview
⬥ Use 
on floor the tick after 
's voiceline appears in chat box. If playing with audio, this is the tick after he says "No..."
⬥ It's assumed that is equipped as much as possible while its spec is active. For more information, type !fsoa in #bot-commands

Sunshine Cooldown Issues on P1 → P2 Transition
If pushing faster times, cooldown will be an issue as it delays your ability to use early in P2. If this scenario is encountered, using early is the solution.
⬥ Option A - more time in P1 sun, slower warp
Use the above rotation, and simply swap and
⬥ Option B - less time in P1 sun, faster warp
the tick after spawns on the balcony → 
→ floor → (tc) → continue as per above
Depending on where Kerapac phased during P1 you’ll have to somewhat loosely use one of these rotations:
⬥ Before/After jump 1:
→ (as he raises staff) → 
→ → → 
→ → → Walk under + → 4 hit → → → ( end) → 4 hit (switch to 
) → → → →

⬥ After jump 3:

→ 1t after warp →

→ → / filler basic (if not phased into p3) → → → 
→ Improvise
(Try to use and before the 2nd hit after shatter to avoid cooldown issues during p4, refer to the video below if you're struggling)
⬥ Echo 1
→ → between two echoes → → → → (DW) → (if needed, use on 2nd echo if unneeded)
⬥ Echo 2
→ → (if tsunami is on cooldown then use it once off cooldown/skip) → → →
⬥ Echo 3
to third echo → → + between echo and Kerapac → → → → 
→ → → (if needed, the echo dies by the quite often so use on kerapac if so)
⬥ Kerapac
→ (skip till here if 60%+ adren) → → → ( end) → Improvise
(Try to save for the next kill)
