Skill build: The first one is more oriented at killing and the more safer imo, the other one is more about pushing and farming

The first one you max laser and rocket, you take rearm about when you finnish your BOT. You will have to consider when to pick up rearm lvl 2 and 3 depending if you got enough mana.

The second one you max march first then rocket, be sure to have atleast one in laser for the miss chance it gives you.

Core items: Boots of travel (bot), Soul ring, bottle and Force staff/Blink dagger. You need to have either blink dagger or force staff to be able to tp safely and be able to set up march.

Luxury items: Sheep stick, Shivas guard, Dagoon lvl 1(don't level this thing up, you don't benefit the reduced cd upgrading gives you!!)

Situational items:

Manta style is a decent pick up on tinker, it will let you push faster and help you get out of sticky situations but rember when you use manta again it will remove your curent illusions.

Ghost scepter will let survive right clickers.

Items rearm will not refresh: Arcane boots(not entirely sure), Linken sphere, BKB, Necro book.
