Whether a Long sword +4 tempering fire? (Dark Souls 3)

Direct hamlet's dilemma - to temper or not to temper) Annealing is a very situational damage though, and cut, but against enemies with a weakness to fire will be just right. But essno against immune to fire is not a ride, so it is better to have a spare stick in this case. Hardening is always possible to remove/perezalit, so try it, experiment.

Such hardening, as the fire to do is just in the beginning of the game. Generally the top quenching are agile and heavy gems

Advise on solstice see there's an example of pumping and quenching of all weapons in the game with the damage parameters of the skills and clear demonstration.

none of these games makes no sense at all to harden to the elements, because the largest percentage of damage is always physical.

Never pinned the weapon to the element, because she(Eroica) universal, and you yourself with the scroll could give her stat she does NOT lose PHYSICAL damage and gets extra damage for a while(element) in the reverse case hardening PHYSICAL damage goes negative(which is not always good) well, if you're an UBER nerd and you love to pass the game 100 + times then you can temper all arwiki in DIFFERENT ways and to carry Ala on all occasions...
In short - if tempered now useful, and then WITHOUT useful and you will then regret how much you fucked up -_- . Stupid + stats.

Better not, better Cali those that improve physical damage, and the rest is resin, well abaut element and quickly applied, those that are smaller are applied very quickly on the weapon, another plus the visual effect of the resins or buff spells on the weapon.

Sharpening into the fire early in the game at the time, as the stats are crappy and the enemies weakness to fire. But closer to the middle of the game after about swamps need sharpening in the build. But for pvp I do not recommend.

it is better not to temper but to use ointment
the sword is the same but the additional effect is always according to the situation
