Rohana by Zeratul67

Level 1: On this tier all talents will substantially change how Rohanna is played, and is the cornerstone of the main build themes.
Time Reversal: Time Warp heals allies and speeds them up by the same amount. Gain 1 Mana for every Non-Structure enemy hit by Time Warp.
Meditation: Accelerate Mana Regeneration and Cooldowns on Q, W and D by 50% while Dimensional Shifted.
Khaydarin Resonance: ? Quest: Regeneration Globes grant an additional 50% Mana.
? Reward: After collecting 15 Regeneration Globes, Plasma Shield's value is increased by 15%.
? Reward: After collecting 30 Regeneration Globes, Plasma Shield's value is increased by 30%.
Math: old maximum is 665 shields, new is 650. Keep in mind permanent shield talent exists in this kit.
Preserver's Will: ? Quest: Attacking enemy Heroes restores 8 mana per second.
? Reward: After spending 30 seconds attacking Heroes, Distortion Beam's damage is increased by 125%.
? Reward: After spending 60 seconds attacking Heroes, Distortion Beam's range is increased by an additional 1.

Level 4: Here you choose the kind of support you want to be: Health sustain, AA enabler, Damage mitigator
Khala's Sanctity: Plasma Shield grants 20 (+4%) HP/s health regeneration for 12 seconds. This effect does not stack.
Khala's Embrace: Plasma Shield grants 60% life leech on auto attacks.
Khala's Light: Plasma Shield can retain 40% of its remaining value indefinitely (and stack up to 140% if recast, just like the old KE, except less shields). If a shield takes no damage until it expires (goes down to 50%), refresh cooldown of Plasma Shield.

Level 7: Safety and precaution talents
Psionic Projection: Increases the cast range of Plasma Shield and Time Warp by 40%.
Shieldmaiden: Casting Plasma Shield on an ally casts one on Rohana for free.
Prescience: Dimensional Shift gains a second charge
Mental Acuity: ? Quest: Each Takedown earned lowers the cooldown of Oracle by 3 seconds, to a maximum of 15 seconds.
? Reward: Upon getting 5 Takedowns, the sight range of Oracle is increased by 50%. Rohana gains 25 armor while using Oracle

Level 10: Ultimates

Force wall is pretty much the same. Rohanna's greater amount of slows makes it slightly more powerful.

The other ult, Rememberance is fairly similar to abilities like Crystal Aegis, Divine Palm or Ancestral Healing (on lvl20 even Resurrection). The effectiveness of it is a lot more situational, and by its nature it is anti-burst. The interesting thing is that you can use it on enemies to negate one of the above mentioned saves, or just to lock someone down for 2 seconds. It also has interesting implications with buffs, it is possible to prolong buffs like Bloodlust for a much longer time with this, while keeping a bruiser type hero safe.

Level 13: Defensive talents
Deep Shift: Dimensional Shift duration and Movement Speed bonuses are increased by 50%. It also heals for 25% of Rohana's full health.
Resonation: (moved from level 7) Distortion Beam slows enemies affected by Time Warp by 45% (+25% on time warp = 70% slow in total).
Time Dilation: Time Warp expands to a 75% larger radius over its duration.
Nullification: Cooldown: 60 seconds
Activate to reduce the damage the target enemy Hero deals by 75% for 4 seconds.

Level 16: W talents for build synergy or situational utility
Double Bubble: A second Time Warp can be cast within 2 seconds of casting the first.
Phase Disruption: Enemy Heroes being hit by Time Warp have their Physical Armor reduced by 25, causing them to take 25% more damage from Basic Attacks.
Focused Beam: Basic Attacks against Heroes affected by Time Warp deal an additional 1% of the target's maximum Health as damage.

Level 20: Ultimate utility tier
Living Memory: Reduce cooldown of Memory Preservation to 80 seconds. Can now be used on dead heroes to return them to life for 5 seconds after their death.
Force Barrier: Force Wall's Range is increased by 100% and its cooldown is reduced by 5 seconds.
Prismatic Link: Basic Attacks bounce to hit 2 additional targets for 50% damage.
Shield Battery: Cooldown: 60 seconds
Activate to give all nearby allied Heroes an untalented Plasma Shield.

Solo Healer: This build heals through Q, W and R and has the best sustain with decent burst mitigation and good peel.
1: Time Reversal, 4: Khala's Sanctity, 7: Psionic Projection / Mental Acuity, 10: Rememberance, 13: Time Dilation / Nullification, 16: Double Bubble, 20: Shield Battery / Living Memory

Secondary Support: This build provides no sustain, but adds permanent shields and has the best burst mitigation.
1: Khaydarin Resonance, 4: Khala's Light, 7: Psionic Projection, 10: Situational, 13: Situational, 16: Double Bubble / Phase Disruption, 20: Situational

AA Build: The most similar to the current Tassadar's AA build. Lower overall (spell) damage, but more utility (more slows + copied shields).
1: Preserver's Will, 4: Khala's Embrace, 7: Shieldmaiden, 10: Force Wall, 13: Resonation, 16: Phase Disruption / Focused Beam, 20: Force Barrier / Prismatic Link

Survival Build (Racecar): This build can spam a lot of abilities due to the Dimensional Shift synergies and is the best utility build that juggles its survival abilities for more support. This is also viable as a secondary support if she'd be targeted a lot.
1: Meditation, 4: Situational, 7: Prescience, 10: Situational, 13: Deep Shift, 16: Double Bubble, 20: Situational

These builds can be mixed and give up some synergies for other utilities. For instance a main healer of an AA heavy team might want to get Khala's Embrace instead of Khala's Sanctity.
