I do Kaiser for 2 hand and Demon Slayer for 1 hand, both take me (I timed it) 25ish minutes.
I made level 0-10 gear with traces (70%) and made a weapon same way. This helps a ton and will cost you under 2 mil to make.
First I load the items onto my characters, this can be done with a second computer or by simply asking a friend to help, Load equips, some pots (I use power elixer and I've never used more than 3 per Kaiser while leveling up) and also 2 town scrolls.
Then I go to the Mage town (To lazy to look up how to spell it) go to Evil eyes and kill there until level 15, then go one map to the left to cursed eyes and kill till level 30 (You get a ton of elite mobs here and even a few bosses) after that use town scroll and go to mage place, use cab to sleepywood, go to gold beach, go one map left and look for a swiftness rune, use it and you'll hit 33 in no time.
I've done this a little over 30 times so far, for me it's a ton faster than golems (I don't have kanna and HS and I still get close to their times) ^^
Try it out for yourself, remember to have the gear though, the added HP and stat is great.
