|Tiki's refined breath opens up some more options for her, including a powerful one shot build.
Tiki's best boon for this build is +Atk, followed by +Def. Attack gives her more one shot potential, especially against green dragons who can threaten her due to her low speed and mild resistance, while Defense helps her soak up physical hits. Resistance isn't necessary, as she is able to OHKO green tome threats and green dragons, given the effective damage her weapon provides. Her best bane is -Spd, as she doesn't really need the speed and it's already low enough.
Breath of Fog provides a defensive option for Tiki, especially on enemy phase due to her easy condition to get the Atk/Def Bond 3 at two range effect, as well as effective damage against enemy dragon foes. These two factors combined make Fog Breath capitalize one her strengths, tanking physical attacks and hitting back extremely hard, while also patching up her main coverage weakness: opposing dragons who can either outspeed her or otherwise double her. If you do not plan on running another dragon or sword on your team, any stat refine of your choice (besides speed) works well.
As a frontline tank, Reposition is the optimal choice for an assist, though this choice can change based on what your team composition wants. Though, like other movement skills it can be switched out for a double rally for points.
Bonfire is a fairly standard special choice for Tiki, especially because she comes with it, and she can activate it on her first combat. Alternately, Ignis is also a strong choice for her, as most of the time Tiki doesn't even need a special proc to kill her first enemy, and thus she is primed to attack on her second combat.
- A Skills
Distant Counter is a very generic, albeit extremely powerful, A skill, allowing Tiki to counter attack versus ranged units. Due to her weapon hitting the lower defensive stat, tagged with her great attack, she can OHKO most mages on the counter attack, making this a great skill for her.
- B Skills
Quick Riposte 3 is essential for allowing Tiki to duel bulky units, as she has an abysmal speed stat. While Tiki has some OHKO potential on player phase, she will mostly be attacking on the enemy phase, so Quick Riposte easily becomes the skill of choice.
Alternately, one can go an alternate build such as Wrath 3. This is similar to the Ignis build, but utilizes the special Aether instead, using the -1 CD below 75% HP to have an empowered Aether on the second attack, allowing Tiki to also heal up.
Tiki can also opt to cross over into sword counter territory by running Swordbreaker 3. Due to her impressive bulk, she can generally tank a single sword hit and then kill them using her two attacks. This also lets her cross into player phase territory against sword units, adding extra flexibility to how she can be played.
- C Skills
For a C skill, Tiki can take anything, but Panic Ploy 3 is advised if you're not running the skill on someone else already. Other possible choices are Infantry Pulse 3 given her high HP pool or just any Hone/Fortify/Spur/Drive of your choice.
- Sacred Seals
Tiki's seal slot is pretty open. Defensive options such as Close Def 3 and Distant Def 3 are always strong choices. Alternately, especially if you are running Aether, Heavy Blade 3 works well on Tiki, giving her a way to accelerate special cooldowns without a Breath skill.
If you are not running Quick Riposte 3 as her B skill, you should instead run it as your seal.
