The reason I don't take a trinity force is because I feel like I do more damage with this build rather than using a tri-force, but if you want to change anything go for it. Summoner spells are really interchangeable but the ones i recommend are: Garrison, flash, ignite or ghost.

wut summoner spells do u recomend and wuldnt a trinity force be good for burst?

Well Thanks for your support! Everyone has their own opinion, but this one is meant to be an assassin! So many people say they build her tanky-dps. I usually do that too, but in dominion you need agility... Not tanky-dpsness. This build is an assault build, not a defender build. Her move speed is core to the gameplay in dominion.

i tried this and did terrible, but this builds her more like an assassin and less of a tanky dps personally i prefer boots>trinity force>merc treads>atmas impaler>warmogs armor>(force of nature/ or guardian angel armor) with the atmas as you get tankier you just get more ad, i like it.
