Gavial is a 4★ Medical Medic who specializes in (obviously) Healing and is available in the Credit Store after the player has purchased the first copy of Courier with five additional copies of her available (for the purpose of giving out 
Gavial's Token) as the player spends more 
Credit. As a Medical Medic, Gavial heals one target at a time with a range of 3×3 tiles with a 1-tile extension in front that is improved to 3×4 tiles at Elite 1.
Gavial's skills improve the efficiency of her healing:
- The first skill, Vitality Restoration, applies a short-lasting effect on the friendly unit healed by Gavial when fully charged, which restores additional HP equal to a portion of Gavial's ATK per second, with the effectiveness doubled when the friendly's HP falls below 50%, and can stack two charges from Level 7.
- The second skill, Vitality Restoration - Wide Range, functions identically to Vitality Restoration, but it is manually activated with a higher SP cost, affects all friendlies in Gavial's healing range, and lasts longer, although not as effective when the friendlies' HP haven't fallen below 50% yet but more effective when it have.
Gavial's talent, Battlefield Medic, buffs the ATK and DEF off all deployed Medics (including Gavial herself) for a short time after she is deployed.
Gavial's PHY-Y Operator Module, "Follow Your Doctor's Orders", increaeses her healing effectiveness by 15% when she heals friendly units on melee tiles, in addition to increasing her maximum HP and ATK; once upgraded, Battlefield Medic's duration is extended.
Gavial's first base skill, Pharmacology α, increases the byproduct rate of upgrade material processing by 75% when she is assigned to the Workshop. Her second base skill, Medic Expert α, speeds up the skill Mastery training of Medic Operators by 30% when she is assigned as a trainer in the Training Room.
Overall, Gavial is a solid Medical Medic who is not only easily accessible for all players, but also perform well to counter a steady stream of damage, making her a good choice for most situations.
