| Skill Name | SLv | Category | Type Scope Range |
Power | Hit% | Cost | Effect(s) |
| Stone Memory | n/a | Mag. Attack | Rock One Mid |
100% | 100% | SP12 | 20% chance to petrify. (Cannot act) |
In addition, Harden will upgrade to Grand Crystallize if Stone I is acquired at the Dwarven Forge rather than the Western Graveyard.
| Skill Name | SLv | Category | Type Scope Range |
Power | Hit% | Cost | Effect(s) |
| Grand Crystallize | 30 | Buff Skill | Rock Self |
CT3 | Raises DEF; 50% of the user’s MAG is added to their STR for 3 turns. |
Pick her as your starting character or talk to her in the Western Graveyard and she will join you.
5+ party members will require you to battle Quake III at the Dwarven Forge for her to join.
If you defeat Quake III prior to getting 5+ party members, Stone I will simply be at the Western Graveyard.
Stone I is a defensive specialist and lives up to her name. However, this defensive might is hers, and hers alone; it does not serve to protect her teammates. This is fine in the early game while enemies are not yet intelligent enough to attack anyone but the party member in the front position, but makes her challenging to use as a tank come late game when foes start targeting the rest of the team.
Giving the Revive EX Skill to her teammates, or simply holding out until Stone I has a chance to revive them herself, are both valid tactics which serve as the foundation of the Zombie Attack strategy.
Since Stone I is RANK 1 and has a full 8 EX Skill slots at her disposal, it is quite easy to turn her into a nigh-indestructible dreadnought. Rotating her to the front and clicking guard each turn is simple enough and takes full advantage of her Rock Guard guard skill’s damage reduction, but take care not to allow her AGI to get boosted for any reason lest you squander that advantage. This can also make it tricky to use her when your strategy revolves around lowering the enemy’s AGI. Be sure to keep an eye on her HP as well, as it stands strikingly low compared to her titanic DEF stat.
Another valid use of Stone I is as a blitz attacker by equipping her with a World Reversal accessory, swapping her DEF over to her AGI. This would necessitate finding someone else to fill the tanking role, but there are plenty of good candidates for that should you slot Stone I into the middle or back positions.
The Zombie Attack strategy described above is quite workable since your attackers will fall the moment the wind picks up. Tactical Mode may just be the polisher Stone I needs to truly make her shine.
| What | Why |
| Grossforge | Defense debuffs are great against bosses. It’s also just great to swing around since it has both Water and Stone typing. |
| Whiteslash | HP Autoheal (L) and Cover are the perfect skills for a tank to have. |
| Flip Phone | Only available through carrying over data from playing Kiito’s previous games, which at the time of writing, only Wind I Creator is in English. However... If you do know the passwords for the other two games, this weapon is an absolute gem for Stone I since it matches her in type. |
| Crush Mace | Destructive Joy is such a great skill for softening up the enemy. Stone I has great defensive power even without guarding, so having her beat down foes with this isn’t a terrible choice if you just don’t care. |
| Drill Spear | Matches Stone I’s typing. Its debuffing effect has a 100% activation rate. It’s just the ticket for weakening the enemy. Just don’t forget to seal Stone I’s Build Up passive before using it. |
| Duplex Greatbow | Another great Rock type weapon for the Rock type girl. Offers excellent single-target damage and has a nice buff when situated in the rear position. |
| Noble Bow | Stone I has nothing to fear about recoil from Holy Rage, so go wild. The only problem is its typing: Dark/Light. That makes it tricky to use. |
| Plasma Spike | Paralyzed foes have a harder time hitting you, which in turn makes your party harder to kill. Paralyzed foes are also easier to hit. The downside is that Stone I will likely be faster than Paralyzed targets, worsening her Rock Guard’s potency. |
| Shield of Tower | Lets Stone I LARP as Leaf Barrier & Electro Barrier with a physical-only version of Wide Guard. This is exceptionally handy since Stone I otherwise lacks a means of drawing aggro away from her teammates. |
| Large Shield Tower Shield |
Nullifies crits while defending. This is great since crits ignore guard skills and are the #1 killer of party members in ENCHANT FARM. |
| Psycho Rage | Nullifies crits all the time and has complete immunity to status ailments. The downsides? HP drain hurts. And the status immunity is reduced to half resistance when used in Tactical Mode. |
| Imperial Cross | Nullifies crits. Not available during a first playthrough. |
| Flat Trap | Paired with a Spike Shield or Plasma Spike, you can kill a surprising number of bosses just by sitting there and defending. Is it fast? Nope. Does it work? Sure does. Damage dealt is based on the foe’s max HP. |
| Evolution Stone | She already boasts absurd defense. This makes it laughably high. |
| World Reversal | Sacrifices DEF to gain incredible AGI. This makes her great as an attacker or a supporter. |
| Life Sphere Liferisk Orb |
No downsides since Hard-Headed nullifies recoil. Just be mindful that the Liferisk Orb only works for single-target. |
| EX Skill | Why |
| HP+ DEF+ |
All of these serve to improve her tanking. |
| Guard Power | |
| Auto Recovery | |
| Resistance Auto Cure |
|
| Type Affinity Bash Mastery MAG+ |
Vital if she will be attacking. |
| Affliction | Useful for getting Stone Memory’s petrify to proc, as well as any other weapon skills with status ailments Stone I might be carrying. |
