To maximize your progression efficiency in Summoners War, you must prioritize maxing skills that reduce cooldowns and increase harmful effect activation rates on your core PvE farmers and dungeon teams, starting with Veromos (Dark Efreet) and Belladeon (Light Inugami) before investing precious Devilmons into nat-5 luxury units.
Understanding Devilmon and Skill-Up Economy
Managing your rare resources is the single most important habit for free-to-play and low-spending players. Devilmons are scarce items earned through weekly Arena glory shops, events, and ToA (Trial of Ascension) clears. Never waste a Devilmon on a monster that can be skilled up using fusion monsters or lower-element duplicate 3-star and 4-star units.

When evaluating which skill to max first, look for three critical markers: Cooldown Reduction (-1 Turn), Harmful Effect Rate (+10% or +20%), and Damage Increases. Cooldown reductions are almost always the absolute highest priority because they drastically increase your team's turns, healing uptime, and debuff coverage during brutal dungeon runs like Giant's Keep (GB10/GB12) and Dragon's Lair (DB10/DB12).
Veromos (Dark Efreet): The Ultimate First Priority
Veromos is universally recognized as the foundational fusion monster that carries players through early game DB10, GB10, and ToA Normal. You should feed Devilmons to Veromos immediately until his skills are fully maximized, with a very specific order of operations.
First, target his second skill, Mega Crusher (Super Crush). Maxing this skill reduces its cooldown by one turn and increases the stun activation rate. A shorter cooldown means constant crowd control against trash waves in dungeons, mitigating incoming damage significantly. Next, work on his first skill, Crush, to increase the Continuous Damage (DOT) activation rate. While his passive, Cleanse, does not take skill-ups, maximizing his active skills transforms Veromos from a basic cleanser into an offensive engine.

Belladeon (Light Inugami): Support Skill Maxing Order
Belladeon is a farmable Secret Dungeon monster that remains relevant well into late-game PvP and PvE content. Unlike natural five-star units, Belladeon is skilled up using easily farmable Inugamis found in scenario maps or Secret Dungeons, making skill-maxing straightforward.
Your absolute priority for Belladeon is her third skill, Mobilize. Maxing Mobilize reduces its cooldown from 4 turns to 3 turns and boosts the attack bar recovery by an extra 10%. Having an AoE heal and a 30% attack bar boost on a 3-turn cooldown is game-changing for keeping your team alive against the Giant. Once Mobilize is maxed, focus on her first skill, Scratch, to guarantee the Defense Break (Armor Break) effect on the boss. Defense break is mandatory for lowering run times across all Cairos Dungeons.
Sigmarus (Water Phoenix): PvE Damage Dealer Investment
Once your cleansing and healing foundations are secure, your next major milestone is fusing Sigmarus to drastically accelerate your Giant and Dragon dungeon clear speeds. Sigmarus relies heavily on Max HP scaling damage on his third skill, Frozen Prisma.
You should pump Devilmons directly into Sigmarus until both Ice Volcano (Skill 2) and Frozen Prisma (Skill 3) are fully maxed out for maximum cooldown reduction. Shorter cooldowns on Sigmarus mean continuous execution of percentage-based HP damage against boss waves, shaving precious seconds off your runs.

Colleen (Fire Harpu): Raids and Necropolis Essentials
As you transition from early dungeons into Necropolis and Rifts, Colleen becomes a non-negotiable support pick. Because she is a 2-star native monster, you can max her skills entirely through unknown scrolls and scenario drops without spending a single Devilmon.
Prioritize maxing her second skill, Multishield / Light of Friendship (Heal and Attack Buff), to ensure 100% uptime on the attack power buff and healing over time. Following that, max her first skill, Wing Beat, to guarantee the Attack Power reduction debuff on enemies. Keeping the boss's attack broken is the core survival mechanic for Rift Raids.
General Rules for Skill-Up Priority in Summoners War
To summarize optimal decision-making when allocating skill points across your entire monster box, always adhere to the following operational hierarchy:
- Priority 1: Cooldown Reductions (-1 Turn). Any skill that lowers cooldowns takes precedence over raw damage increases.
- Priority 2: Debuff Activation Rates. Skills that apply Defense Break, Attack Break, Stun, or Continuous Damage must reach 100% activation probability (including accuracy checks).
- Priority 3: Healing and Buff Scaling. Increasing heal amounts or extending buff durations.
- Priority 4: Flat Damage Increases. Leave pure damage percentage increases for last, as base stats and rune quality dictate ultimate damage output.
By strictly following this skill maximization sequence, you will avoid wasting valuable Devilmons and drastically shorten the grind required to build stable, sub-two-minute auto teams across the entire Com2uS ecosystem.
