This is my build + a short explanation to why I chose these items:
Clock of Destiny - This Item gives Odette a good amount of HP and Mana as the game progresses. A very solid starting item. Particulary good for Odette because of the additional health, which will allow her to take more damage during her ultimate.
Arcane Boots - Self-explanatory, geared towards damage.
Lightning Truncheon - Power spike item. The damage starts to show after this item is acquired. The mana regen is also quite useful for sustain in lane and skill spamming.
Holy Crystal - Now we're talking! You get magic power for days and some seriously damaging skills.
Ice Queen Wand - I have geared most of my items based on magic power and damage, but I find this item to be important. The slow on this item's passive will make enemies harder to run away from your ultimate, as well as slowing enemies from getting too close to you. Overall, this item really is the icing on the cake (really funny, I know).
Blood Wings - A no brainer for Odette. This item beefs her up to sustain more burst damage, which during end game can be quite scary.
Battle Spell - Flicker, Iron Wall, Weaken
Tips and Tricks
- General Tip: Basically, in team fights you want to play in a way that you are not the focus of (at least) most enemy attacks. This is true for almost all mages, but I do notice that some people assume the ult will make her tanky enough to tank. She is still quite a squishy character, and should be used with some caution. If you do find an enemy focusing you, remember to use your 1st and 2nd skill to poke down/cc the opponent before you ult.
- Don't be alone: Even though the build provided gives a good amount of health and sustain, Odette is still quite easy to kill when alone. Her skills are meant to be used in a team fight, and she benefits immensely from her team's crowd control.
- Use Odette in a CC team: Her abilities are heavily compromised when her team lacks the CC to keep the enemy within her ult (and also hopefully away from attacking her). If your team lacks strong CC, it may be wise to choose another character.
- Use Ultimate when enemy has engaged or has been crowd controlled: this is a bit of a newbie tip, but do not use ultimate when the enemy can easily get away. The idea is to activate ult when the enemy is forced to stay in ult and fight, or die if they attempt to get out.
- Auto-Attack after using skill: Take advantage of her passive! Don't just spam every skill in succession, remember to use auto-attack after each skill.
- Skill 1, Skill 2, Ult: Skill combo, using skill 2 then ult will ensure that at least one enemy will have a hard time escaping.
- Flicker ult: As many players mentioned, if you run the Flicker battle spell, you can flicker in a team fight for a better position to ult (this could also be useful against low health enemies running away from a fight). Just remember not to flicker in without your team already in the fight. You are not Rambo and you will suffer...
- Try not to use ultimate on one enemy: This is situational, but for the most part do not activate ultimate when there is only 1 enemy in sight. Your 3rd skill has a long cooldown, and the chances of getting ganked while trying to kill that one enemy is quite likely. If you use ult trying to kill that one person, you will have nothing for the rest of the opposition.
- Lay low early game: Odette is quite weak both health and damage-wise during early game, so farm and lay low until mid-late game, where her ultimate would melt the enemy in team fights
