The PvP meta in 'Seven Knights Re:BIRTH' (hereinafter SKRB) is currently undergoing a seismic shift, triggered by the arrival of the new Old Seven Knights. As fresh legendary-grade heroes enter the fray, the established veterans are being pushed aside, clearing the way for a variety of new meta decks. Millia was the first to make waves, but as she began to dominate, today’s protagonist, Gelidus, arrived to keep her in check. His synergy with the recently released Phlanis is particularly noteworthy, and his performance rating is climbing by the day. If you are a fan of the latest tank-heavy defensive builds, I suggest you read today’s analysis closely.

Q. What skill upgrades do you recommend for Gelidus?
A. Aside from basic attacks, I recommend upgrading all skills that increase the 'Frost' probability.

Gelidus’s skill kit is packed with effects worthy of an Old Seven Knight. Let’s first look at the passive 'Blessing of the Ice Queen,' which boosts the entire team’s durability just by being in the lineup. Simply slotting Gelidus into your formation applies an 'Effect Application Probability Decrease' to all enemies. Unlike 'Effect Accuracy vs. Effect Resistance' mechanics, this directly shaves off the application chance, nipping unpredictable variables in the bud.

It is particularly effective at shutting down the early build-ups of Melkire, who relies on wide-area stun, or Millia’s dodge-heavy decks. Unlike Elicia, who tends to provide support after debuffs have already landed, Gelidus raises the threshold for status effects before they even hit. Consequently, he serves as a robust counter against opponents who rely on queued skill strategies.

Frost, the core status effect of Gelidus, triggers on all skills, including basic attacks. Even his passive involves it, with a probability ranging from 50% for basic attacks to 75% for his passive—a sensible middle ground. The real variable here is the passive: upon using a skill twice, he has a 75% chance to inflict Frost on three enemies. When combined with his skill-based Frost, the perceived probability is incredibly high.

For instance, if Gelidus uses one basic attack and then fires off 'Tyrant’s Memory' (which has a 70% Frost chance), you are effectively attempting three Frost applications. Since the skill hits twice, each strike triggers a potential status effect, and the passive’s 75% chance kicks in as well, locking the opponent’s movement in a relentless chain.

Q. What makes the passive buff of Gelidus so unique?
A. It’s the 'Block Probability Increase proportional to Defense'.

Thanks to the aforementioned Frost mechanism, Gelidus truly shines in prolonged engagements. If you intend to exploit the lack of sustainability in glass-cannon compositions, pairing him with defensive and healing synergies like 'Rudy' or 'Elysia' is a smart move. His survival is primarily bolstered by that 'Block Probability Increase proportional to Defense.'

The maximum block probability you can secure here is 27%, which can be pushed to 33% with the passive skill upgrades we discussed earlier. Keep in mind, you will need exactly 1,650 Defense to hit that ceiling. Conveniently, his skill coefficients scale with both Physical Attack and Defense, allowing him to be a dual-threat tank. Plus, since he recovers 100% of the damage dealt whenever he inflicts Frost, a single defensive build provides a massive range of benefits.

Q. What is the ultimate high-end defensive build for Gelidus?
A. A 4-piece Guardian set, with 'Defense (%)' weapons and damage-reduction armor.

When building a tank as naturally sturdy as Gelidus, there is one thing you must be careful about: the Defense stat I mentioned earlier. Because his block probability scales with this value, Defense carries significantly more weight on him than on other heroes. Remember, you need at least 1,650 Defense to reach that 33% block cap.

The most efficient way to achieve this is via the 4-piece Guardian set combined with a 'Defense (%)' main stat on your weapon. While some might consider building for Effect Accuracy to counter the opponent’s resistance, I strongly recommend prioritizing survival. Trust the passive’s application probability reduction to do the heavy lifting, and pick up extra Accuracy from your sub-stats.

Gelidus is primarily a PvP specialist. Whether it’s Guild Battles, the Arena, or Total War, the fundamental strategy remains the same, so sticking to one build is perfectly fine. In fact, there is no need to swap your gear for PvE content either. Many adventurers are currently using Gelidus in the recently expanded level 15 Fire Element Dungeon, where he clears content with ease. The freedom of his build, once you hit that 1,650 Defense threshold, is one of his greatest assets.
