hi there, my name is Rick. also known as DutchWarBanner on MOBAFIRE.
this week i'll be showing you a build for orianna, just like i build her.
i feel like she is a very strong caster. so i'll give you, a guide for orianna.

ps: i am new to MOBAFIRE, not with reading, but this is my first guide i've made.

I start off with q, it does damage and you can keep your enemy's off your farm.
this way your (mid) lane enemy cant get gold so fast. this is a exelent way
to start the match.

after you reach lvl 4, u got all of the low level spells, so u can start harrasing!
first u shoot ur q on him, then press w imidietly after, then e.
(the e is not necessery, but it gives a nice shield and does damage).

with ur ult, you can save yourself and your teammates, but you also do alot of damage
and you pull them back and stun them, so you can do even more damage.

since u know i am new, u would understand i dont yet understand scripting and stuff,
so i'll just explain what i build, whta combo's i use, and what spells i take.

i hope this (simple and short) build will help you playing orianna as an 'AP Slayer'!
