Grunid guide: skills, build and team roles
Overview
Grunid is a Rare Water Ranged Attacker from the Stonehearts Faction in Invokers: Titan Legacy. He hits one enemy very hard from a distance and then makes the whole team hit that enemy harder. Drill Rocket is his biggest Active Skill hit, Rock Exploder feeds his Ultimate Mana, and Pierce The Surface casts Weaken.
His damage scales from ATK. Fully Awakened and before Gear, Grunid has 851 ATK, 591 DEF and 5,144 HP, with 23 Accuracy and 37 Mana Gen. His HP is very low, so he needs a Tank to keep enemies off him.
Weaken raises all damage the target takes, which includes your teammates' damage, so one cast helps everyone. His critical hits matter more than usual, because Rock Exploder gains Ultimate Mana on each one and brings Pierce The Surface around sooner.
He has no healing, Shields or crowd control, and nearly everything he does hits a single target. Weaken needs Accuracy to land.
Skills To Prioritize
Drill Rocket hits one enemy from 9m. It deals 280% of his ATK at Level 1, 526.4% at Level 10 and 560% at Max Level, and the damage rises by 25% at Level 1 and 50% at Level 10 if the target has no buffs. The cooldown falls from 27 seconds to 23 at Level 10 and 22 at Max Level.
Rock Exploder hits one enemy twice, and Grunid gains Ultimate Mana on each critical hit: 15 at Level 1 and 25 at Level 10. The cooldown falls from 26 seconds to 22 at Level 10 and 21 at Max Level.
Pierce The Surface, his Ultimate, hits one enemy for 472.5% of his ATK at Level 1, 888.3% at Level 10 and 945% at Max Level, and casts Weaken: 10% for ten seconds at Level 1, and 15% for 16 seconds at Level 10 and Max Level. It needs Accuracy. Its cost falls from 1,100 Mana to 1,050 at Level 10 and 1,000 at Max Level.
Boring Bolt hits one enemy on a ten-second cooldown for 137.5% of his ATK at Level 1 and 275% at Max Level.
If you want Grunid to deal the most damage, upgrade Drill Rocket first, as it reaches 526.4% ATK at Level 10 and the unbuffed-target bonus grows to 50%. If you want him to help the whole team, upgrade Pierce The Surface first, as Level 10 casts 15% Weaken for 16 seconds and Max Level lowers the cost to 1,000 Mana.
Build And Team Support
Build Crit Rate to around 75-80%, then as much Crit DMG as the build allows, because Rock Exploder's Ultimate Mana only comes from critical hits. Weaken needs Accuracy to land, so put Accuracy on your Chestplate and your Flask. Mana Gen on your Talisman helps him reach Pierce The Surface, which still costs 1,000 Mana at Max Level, and Skill RECOV brings back Drill Rocket, his hardest-hitting Active Skill.
For Relic Sets, Crit Rate Relics make his critical hits more reliable, Crit Damage Relics and Predator raise how hard they hit, and Accuracy Relics help Weaken land. Mana Relics help him reach his Ultimate sooner, and Fury Relics bring back Drill Rocket sooner. His native Blight Tolerance already covers one Corruption on Ulgorim and Koltmos, so check which Tolerance Relics a Boss needs before adding any.
Pair him with a Tank, because his HP is very low, and with a healer to keep him alive while he casts.
Arena, Bosses And Spires
In Arena, Pierce The Surface's Weaken lets your team burst down a single target, and Drill Rocket punishes enemies that have no buffs. Protect him from early burst, because his HP is very low, and be wary of enemy Invokers with Immunity or Skills that remove debuffs, as they can wipe out Weaken before your team uses it.
Against Koltmos, Ranged Attackers are the key, and Grunid's native Blight Tolerance covers one of his two Corruptions. Against Ulgorim, his native Blight Tolerance covers one of his two Corruptions and Weaken raises the damage your team deals. Against Light Omnissi, who wants attack output rather than healing, his Blight Tolerance covers one of her two Corruptions and Pierce The Surface hits her for 945% ATK at Max Level.
Against Sedula, Pierce The Surface casts Weaken on her, which raises all the damage your team deals in her 60-second window. His Skills hit only one enemy, so other Invokers must clear her Tentacles. Sedula changes Element every day, and Grunid has Elemental Advantage on the days she is Fire.
In the Water Spire, Pierce The Surface weakens the target your team is focusing. Pair him with Invokers of a similar Rarity: Rufin, a Rare Water Support, casts ATK Up and Combo SPD Up and Shields allies, Gohshu the Faceless, an Epic Water Tank, heals, casts Shields and casts DEF Down, and Krakenblood Stonn, a Rare Water Melee Attacker, casts Stun and Move SPD Down.
Awaken
Awakening boosts an Invoker's stats significantly. Bonuses from Relics, Accessories, the Trophy Room, Tactics and Titan leader bonuses apply to base stats and Awakening stats alike, so unlocking the Awakening nodes is critical to maximise Grunid's potential.
Unlocking each Titan node at Star 2, 4 and 6 adds a second to Titan Invokation, taking the total from 12 seconds to 15.
