Ok guys notice allot of you are having trouble with buying items for simple heroes here is some tips.

NOTE: This is how I would play it.

Puck: Puck should get CHICKEN, boots, nulls or STR bracers, bottle, Shivas, silence stick or hex. (Make sure you start spamming spells at level 3-5)
Tide: boots, STR bracers, blink, battle fury. (Treads at some point)
Zeus: Ok Heros like Zeus which is a mana spam hero get boots, Bootle, nulls, arcane ring, hex or silence stick. (Travels maybe also)
Lich: boots, STR bracers, bottle and be the WARD BITCH! Your ulti is all that is needed just have hp to be able to stay alive in battles and you do your job.
Sand King: boots, STR bracers, blink or BKB, battle fury. (Also treads at some point)
Cent: boots, STR bracers, van guards, blink.
Krob, boots, bottle, nulls, blood stone, Shivas.
Slayer: boots, STR bracers, bottle, WARD BITCH! (Gank allot!!)

Lock, boots, STR bracers, ulti ulti, and hex.
Tinker: boots, bottle, nulls, travels, hex.
