Homunculus S
edit- Main article: Homunculus S
NOTE: The section below may be outdated due to numerous changes since it was originally written. Do not be surprised if some of the descriptions differ from the other reputable website contents or current in-game descriptions and/or functions of this system.
Here is a quick breakdown of the homunculus and their uses:
- Eira (Scope: PvM, PvP and MVP) - Being one of the unfavorite Homunculi S that doesn't get enough attention, Eira should by no means be ignored. She has Overed Boost, which temporarily provides her owner with ludicrous amounts of Flee Rate (sets Flee Rate to 500 when mastered), which can make a big difference in dire situations. And in case of a defeat, Eira can be a great backup. With Light of Regenerate, she'll bring her owner back to life. On the other hand, Eira is the fastest Loyalty farming Homunculus S ever due to how Overed Boost can make her hungry really fast. Some of Eira's skills also need certain Loyalty levels, so it's best to breed it from a basic Homunculus that has "Loyalty consuming skills" like Self-Destruction or S.B.R.44.
- Bayeri (Scope: PvM) - A sturdy unicorn with attitude. Bayeri uses Stein Wand to protect his owner and provides Holy property area damage. However, its biggest weakness is that Heilage Stange is interruptable, which makes it an unpopular choice of Homunculus S amongst most Geneticists. Its skills, when not interrupted, can be useful for leveling, but not so useful for much else. Although Stahl Horn could be useful for PvP, there are better options availble to go with.
- Sera (Scope: PvM, PvP, WoE and MVP) - The ultimate all purpose Homunculus S. Sera provides her owner with Pain Killer, a massive damage reduction boost that buys her owner a window of opportunity to defeat an MVP (or another player) without being barraged with massive damage. Very useful for solo PvM as well due to Poison Mist and Needle of Paralysis.
- Best if mutated from Filir for PvM. Vanilmirth is a good alternative.
- Dieter (Scope: PvM, PvP, WoE and MVP) - The most popular of the Homunculi S. Dieter provides his owner with Pyroclastic, a significant damage boost, as well as Lava Slide and Magma Flow against monsters. Dieter is very sturdy, which combined with his area ability, makes him possibly the best Homunculus S. Dieter excels at PvM and MVP, which is why it is a big favorite amongst most Geneticists.
- Best if mutated from Vanilmirth or Amistr.
- Eleanor (Scope: PvM and PvP) - Probably one of the least loved Homunculi S, brings the damage but not much else. Eleanor will slaughter any target in sight, by chaining Sonic Claw, Silvervein Rush and Midnight Frenzy for big damage. However, she does not perform well as support, which makes her one of the least used Homunculi S. May have a place in PvP, but then again, some of the other Homuncunuli S skills will prove more useful. She has no area attacks, which makes her fairly useless in PvM except for picking off single targets.
- Best if mutated from Filir.
