1. Well if that's how you feel for little Amistr, then train on an maybe something good will happen in the long run. Reason why I trained 1 was they was cute in a funny way and the fourth skill of theirs when they get loyal (transformed) was pretty good which peeked my interest (though I haven't unlocked that skill yet)
2.If you talking about training just the Amistr, 1 way of doing it (this will take patience an maybe a 2x exp event might help some) change your build to full agi of what you got, just smack a myst case in toy factory an let him beat it to death. He/she will gain the majority of the exp to help him level up at that lvl. Leveling a Amistr is probably the hardest of all the pet classes, they have no attack skills to use only def buffs but all good support pets should be well worth it in the end. Look at the Lif transformation fourth skill, they can add their matk to their str atk to do really high phy damage without losing loyalty, amistr should be worth it also in the long run.
3.Toy factory might be at a slow pace in leveling terms, but its decent in making money and leveling at the same time. Considering if you burn a decent amount of zenny on potions and stuffs, this would be an even balance in training and earning income to later usage. High orcs is a nice spot for leveling up to 85 but they are dangerous in numbers. I don't know what gears you have so I'm just naming a place where it doesn't really require gears.
4.Ho ho ho XD well if you've seen me in niff training my bio or 1 of my friends alchemist, you'd be O.o! Maybe sometimes in game I can show you what I mean.
Its hard to explain how to use it since many people use it either as an on going fire damage post, or as a mob skill. What it is exactly you need 1 Demostration Bottle (not acid bottle) people in prontera vending shops name like AD Shop or something has those Fire Bottles. Everytime you use the skill you use 1 bottle reasons why I like to mob and make the most of 1 bottle. The skill looks like a bonfire laid down like a fire trap, but whatever target that gets close to it takes fire damage and your physical base damage from your stats to do damage at a nice smooth damage rate. The thing is the fire doesn't go nowhere an you have to be standing on it so the monsters can attack you while they are on the fire taking damage (reasons why tanking on the fire). Plus this skill requires cast time an having no dex will be your end, no dex will probably take 3-5 seconds to cast but could kill if your not careful, plus the fire can't be cast on your character tile so casting 2 tiles in front of your character is the technique for it.
