Shiva
Shiva is Snow’s Eidolon. Snow obtains Shiva at the end of Chapter 3 - Lake Bresha (Part 2) after they join him to save him from an onslaught attack of soldiers while he protects Serah’s stasis crystal.
Shiva is the only Eidolon that is technically made up of two different ‘Eidolons’, Nix and Stiria. Both of them are capable of performing their own actions in “Normal Mode”, but they combine to form the single entity known as “Shiva” when Gestalt Mode is activated.
Normal Mode
Each of the two Eidolons, Nix and Stiria, will perform different actions when they are initially summoned into battle. Just like in the Eidolon battle against Snow, Stiria will stand back and perform support abilities and she cannot be attacked directly. From time to time she may deal damage if all party members are healed up, but her primary abilities include:
| Ability | ATB Cost | Description |
|---|---|---|
 Blizzard |
1 | Deal Ice damage to targets. |
| Blizzara |
2 | Deal Ice damage to targets in range. |
| Blizzaga |
3 | Deal Ice damage to targets within a wide radius. |
| Curaga | 1 | Restore a large amount of target’s HP. |
 Esuna |
1 | Remove target’s most recently inflicted status ailment. |
Nix, on the other hand, acts as the more offensive of the two sisters. Its primary attacks include:
| Ability | ATB Cost | Description |
|---|---|---|
| Wheel Rap | 1 | Deal physical damage to target. |
| Flip Kick | 1 | Deal physical damage to target, launching it into the air if Staggered. |
| Wheel Grind | 1 | Strike target repeatedly for physical damage. |
| Wheel Toss | 1 | Attack distant target for physical damage. |
| Pirouette | 2 | Attack surrounding targets repeatedly for physical damage. |
| Blizzara |
2 | Deal Ice damage to targets in range. |
| ATB Charge | Auto | Store power to accelerate ATB Gauge recharge. |
| Penetration | Auto | Bypass target’s Fire, Ice, Lightning and Water resistances. |
Charging the Gestalt Gauge
Helpful Hint
As a reminder, you can charge their Gestalt Gauge by utilizing the same tactics you used to charge their Gestalt Gauge during the Eidolon battle, namely:
- Yields to those who amass chain bonuses. (Both Nix and Stiria)
- Yields to those who defend against and endure attacks. (Both Nix and Stiria)
In other words, you can swap Snow into his 
Sentinel role as an effective method to fill up the Gestalt Gauge. However, this tactic does require the enemy (or enemies) to actually attack Snow and do an effective amount of damage.
Gestalt Mode
Once Nix and Stiria swap into Gestalt Mode, they will have access to the following attacks:
| Ability | ATB Cost | Controls | Description |
|---|---|---|---|
| Wheelie | 3 |  and  |
Charge forward and deal non-elemental damage to target. |
| Spinfreeze | 3 | and |
Deal Ice damage to surrounding targets and launch Staggered ones into the air. |
| Icicle Drift | 3 | or and |
Deal non-elemental damage by sliding into target. |
| Ice Ramp | 3 |  |
Jump off conjured ramp and deal Ice damage. |
| Diamond Dust | All |  |
Repeatedly deal Ice damage to all targets. |
