hi there! i'm luna :) i'm here to update my guide, putting every knowledge i know about Senna here. do note that this guide all comes from my personal experience. there are things said and put here you might not agree with. this is all for fun so i hope you guys who are actually gonna read this find this helpful! <3

to me, Senna is both an amazing support and adc. if you ever fall behind or wanna deal extra damage, her abilities are there to help. she can cc, heal, shield and provide vision which is amazing and she scales very well. i have a m6 mastery on her! 100K+ points, 2700+ takedowns, 200+ epic monsters killed, 300+ structures destroyed and an S+!

like every other champion, she does have cons. she unfortunately can't peel so you have to depend on someone else to do that. she got high cooldowns & mana costs and a weak heal in early game. if the enemy bot lane knows how Senna is like, she can be easily taken advantage of.

imo, you got to have some skills to play Senna. you have to position yourself properly and know when to engage/disengage. you have to be in a safe range when your Q is on a cooldown but also got to AA to reduce the cd. what you build is very important. you, playing Senna, got to know how the enemy team is like. sometimes, you can't go full AD and gotta build utility yk? but eventually, you'll get used to it once you know your way around them.

i have put notes at the item section so do refer them! i like to mix builds rather than go full AD or utility. unless the circumstances are different, always build mythic items first. after you build mythic, what you want to build first is up to you. i'd recommend building a utility item after mythic but it's up to you! just keep in mind the opponent's playstyle whether you want to build Eclipse or Moonstone Renewer! oh and NEVER EVER sell your vision trinkets. vision is important.

there are other items you can build but i honestly like mine. they're really useful! it's up to you on what you want to build, just make sure it's right!

tip on utility items: buy ardent censer, it gives attack speed when you heal or shield which is good for your adc or other allies with AS. buy staff of flowing water if your allies are AP. buy Mikael's Blessing if enemy team is full of crowd control. buy redemption if there a lot of team fights.

because of her high cooldowns, it's best to get items that got ability haste. the higher AH is, the better it is.

Senna's Q, Piercing Darkness, has a high cooldown and the mana costs will increase as the game progresses. you have to use your Q wisely. you got to poke and heal at the right time. she has a weak heal early so it's best if you just Q the enemy and AA quickly. her passive increases the range btw depending on how many mist you collect.

always, Q > AA :)

Senna's W is amazing! you can use your W to either engage/disengage. if morgana is your opponent, let her use her E first before you use your W.

same as Senna's W, her E can also engage/disengage. it camouflages, gives movement speed and hides your team from enemies. it can be used as an escape if used correctly.

lastly, Senna's R, Dawning Shadow! it's an amazing global, AoE ultimate. if you didn't know, it damages enemy, shield allies and provide vision. use it wisely! you can use your ult in the direction of the dragon or baron to see if enemies are there. sadly, it doesn't deal damage to monsters. you also can use your ult to finish off an enemy.

combos:

Q > W > AA
Q > AA > W > AA
Q > W > AA > R

there are many combos you can try out hehe.
and collect as much mists as you can!! it gives you bonus AD, critical chance and life steal :). it gives off 3 gold too. just imagine collecting 100 mists and x3 to that, you already have extra 300 gold. you can get mists of minions, epic and non epic monsters and enemies. :)))))

and that's all! this is all for fun. i just started playing league a few months ago and find it really addicting hehe. Senna is an amazing champion! when played right, you'll see endless possibilities with the redemeer itself. my IGN is h4nak0, you can see my op.gg hehe. i play on EUW. i'm bronze 2 but i hardly play ranked. my WR is not too low but not too high. she's really fun to play. i had bad games and good games on her but that's how i improve on her and able to create a guide on her. play Senna! whether as an adc or support, she's amazing. thank you to whoever will read this! i'll probably come back and update if there are changes to be made. again, this is all for fun! thank you and happy holidays! <3

love,
luna <3
