Fantasy Life i - Interrupting the Heated Phase animation with paralysis
A large part of collectionists' postgame farming is getting the 177 Legendary Don Horns needed to craft every single True Time recipe. Legendary challenges start spawning once the area reaches rank 3 (though they do continue to spawn if you lower the rank afterwards); from ranks 1 to 4, the Legendary Don Woolie only drops 1 horn, then from ranks 5 to 6 it drops 1 or 2 horns (20% of the time), then at max rank 7 it drops 2 to 3 horns (20% of the time)... though with +400% item drop rate equipment across your team, you effectively guarantee the max drops.
At ranks 6 and below, a max-level combat job can pretty quickly defeat the Legendary Don Woolie, so optimizing your strategy doesn't really matter... but at rank 7, even if you maximize damage by using its hidden Dark weakness (x1.6 damage) and stack Dark Damage +10% on your equipment (which, by the way, multiplies your attack stat before enemy defense is subtracted, unlike Charge Damage, wowie), you're still limited by the 9999 damage cap and the Don Woolie's 240,000 HP plus its Heated Phase health recovery, to the point that you're very likely to run out of SP!
One trick (that I read about but didn't need until rank 7), though, is to interrupt the Heated Phase animation, which also cancels the healing. Strangelings like Rouge can inflict paralysis with their skills, and of course the Hunter Life can use para arrows... but since allies are unreliable, and para arrows do reduced damage (and also would likely paralyze before the Heated Phase if used from the start, and I wouldn't have enough time to swap to para arrows then charge then hit before the heal goes off), the best strategy here is actually to simply set Paralysis Bombs + to your consumable hotbar and then use two of them.
(Status inflictions work like Monster Hunter, in that you need to accumulate enough 'status build-up' until you hit a threshold before it finally kicks in... It actually requires two para bombs to hit the threshold, which is why I use one early in the fight and then use the second one during the animation.)
The entire fight only lasts 42 seconds! And it would've been slightly faster if I hadn't missed one volley of charged shots (or if I bothered to use attack buff food/potions and crit rate potions, but whatever). Sure is a shame that I only bothered to grind up the three Legendary Don Woolie areas to rank 7 after I had already grinded for around half the total horns...
