Astels serve as essential companions in Astellia Online, offering combat capabilities that rival the importance of currency like Astellia Asper. Beyond accelerating enemy elimination, these summoned entities deliver beneficial stat enhancements, coordinated combination assaults, tanking functions, and healing support based on your selected Astel lineup. As you progress through Star Rank improvements, strategically chosen Astel combinations within your deck unlock powerful Deck Buffs that significantly impact your overall combat effectiveness.
Register your Astels within designated Deck Slots, typically displayed as a customizable hotbar along your interface’s bottom edge. Default keybinds F1-F8 facilitate instant Astel summoning, with each activation consuming Action Points (AP) as detailed in the Astel Encyclopedia. Maintaining multiple active Astels rapidly depletes your AP pool – when exhausted, your most recently summoned Astel automatically despawns. Savior Astels operate under unique mechanics: they don’t drain AP but feature limited battlefield duration before automatic dismissal.
Astels deploy three distinct skill categories during combat encounters. Standard abilities represent their baseline automated attacks and support functions that trigger without direct input. Combination skills activate when you execute specific character abilities, creating powerful synergistic effects. Forced use commands require manual activation via F1-F8 keys while the Astel remains summoned, with each activation consuming specified AP amounts. Mastering skill timing and resource allocation separates novice summoners from elite Astellia players.
Expand your summoning capabilities through Atra Tonics, obtainable as dungeon loot or purchasable from General Merchants. These consumables enable simultaneous deployment of two Servant Astels, dramatically increasing your combat versatility. Acquire new Astels through main storyline completion, side quest rewards, or dungeon card drops. Each card looted after initial Astel acquisition grants SP (Skill Points) that advance Star Ranks, unlocking higher-grade Star Jewel slots and amplifying overall power.
Strategic farming of specific dungeons yields optimal Astel acquisition rates. Focus on content that provides both card drops and Atra Tonics to maximize efficiency. Newly obtained Astels automatically start at level 1, requiring careful experience allocation to reach combat readiness.
Star Jewels provide crucial offensive and defensive stat bonuses, serving as primary Astel enhancement mechanisms. Access the slotting interface via the Star Jewel button within the Astel Encyclopedia’s Astel page. These valuable items originate from monster drops or Archaeology profession activities, offering customizable stat progression paths.
(While Astels cannot utilize standard character equipment, Star Jewels provide equivalent stat enhancement capabilities.)
Experience distribution extends to currently slotted Astels, with level progression mirroring character advancement but capped at your current level. Freshly acquired Astels initialize at level 1, necessitating strategic experience sharing decisions. Your deck composition determines available Deck Buffs, with specific requirements and Astel combinations listed in the Deck Effect tab. Achieving designated star ranks activates and enhances these buffs, with successful activation indicated by icons adjacent to your minimap.
(Deck Buff activation occurs when cumulative Astel points surpass specific thresholds, rewarding strategic deck construction.)
