Flasks

flasks are like buff potions that can apply certain debuffs to your melee weapons like ichor or cursed flame. you can brew them by using an imbuing station that can be bought from the witch doctor.

they're relatively cheap but can help alot in your battles to either consistently apply a certain debuff or to do sum extra DOT damage

flasks that i recommend:
1. flask of ichor - there are very few mobs that are immune to this defense
corroding debuff which makes this the go to flask to use

2. flask of cursed flame - it does an ok ammount of dot damahe but they're alot of mobs that are immune to it making it kind of useless

3. flask of venom - this post plantera flask imbues your weapon with venom which is one of the most potent dot debuffs in game inflicting -6 persecond but has the same case as cursed flame

Sharpening Station

with the recent buff from 4 armor pen to 12 this makes the sharpening station almost essential to most melee users because in master mode both you and the mobs defense are calculated 100% so having armor penetration really increases dps. i recommend carrying it and favoriting in your inventory so you'll always be able to apply the buff

Wrath and Rage

what more do i have to say 10% damage and 10% crit chance
