Crafting Pet Affixes: as of Patch 3.0, the first 8 Crystals and Topaz can be used on Pets, but costs 5 Crystals. if it takes 5 attempts to change your Pets Element from Ice to Fire, it would cost 25 Calcite. Crafting Pets can get real expensive in Crystals.
Green Garden Build: haha, you are right, Poison ED+ on all items. this was originally posted in 2015, and there have been many changes since then. it looks like you could replace most if not all of them with something else for even more DMG, and to be effective on higher floors. he said it was doing good on floor 700 back then.
WD & ED:
WD% increases Base Weapon DMG. WD+ is added after WD%. doesn’t matter what the Weapons Element is, and they only affect the Weapon they are placed on.
ED% increases DMG of Weapons with the same Element. ED+ is added after ED%. these can be on any item and might be on Pets also. if all Weapons & Items are the same Element, like Fire, then both Weapons DMG is increased by the ED on any item.
if a Weapons BWD is less than 25k DMG, +5k ED is better than +20% ED. if BWD is less than 5k DMG, 5k ED is better than +100% ED. putting WD % & + on your Weapon, increasing Item Quality and Power Stat, your BWD goes up and ED+ becomes less needed/useful, unless you have the extra space for it. for beginners, ED+ is very useful, but for players who have learned how to make better builds, it is less useful, except for PVP Builds.
Adventure Set on Hireling: don’t know. stick an Adventure Set on your Hireling and see if it works when the Gold Pick Up Indicator is activated. or does someone know and want to share?
changing a Weapons Element will not affect WD %/+, but if changing a Weapons Element makes it different than ED %/+ on other items, it loses the benefit of ED on other items until the other items are switched to the same Element. that is why ED is figured after WD.
