Anime Adventures Sky Portal Guide

How to get a Sky Portal

Sky Portals drop at random in Summer Hunt, with no guaranteed drop, and the creator videos we compared agree on that. The rest comes from single sources. One says bosses after wave 25 can drop one, and that finishing the stage can too. Another, reading the update log, says picking harder cards in Summer Hunt gives a higher tier. A single video also shows you enter Summer Hunt from the ship in the lobby.

We found no way to buy or craft one, and we have not confirmed whether Sky Portals can be traded. For the rest of UPD 21 and its Summer 2026 Event, see our anime adventures summer event page.

Which portal gives what

Portal	Where it comes from	What is inside	Source
Sky Portal	Random Summer Hunt drop; one source says bosses after wave 25	20 waves on Sky Island; Star Remnants and SummerPearls	Several creators; wave 25 detail from one source
Sky God’s Portal	Chance reward for clearing a Sky Portal	Sky God; sources disagree on whether a clear guarantees it	In-game quest name; route from several creators
Explosion Mage’s portal	Chance reward for clearing all 50 Summer Hunt waves	Explosion Mage	Creator videos

The quest menu uses the name Sky God’s Portal, and one event quest asks you to clear your own as host.

Every portal in UPD 21

Portals have their own Portals tab in the inventory, as the item screen showed on November 3, 2026. In the creator videos we compared, others can join a portal you open, and each portal panel lists its own modifiers, such as regenerating enemies, along with its difficulty and reward multipliers. Read that panel before you start a run.

Sky God’s Portal is a chance drop for clearing a Sky Portal, several videos show. One source, which got one from a Tier 11 clear, reports that higher Sky Portal tiers raise that chance. Sources disagree on what clearing that portal gives: one creator who cleared their own says Sky God was guaranteed and goes only to the portal’s owner, while a video reading the update log says it promises only a chance. Either way, open it yourself as host if you want the Sky God quest to count it.

Several sources agree that Explosion Mage’s Portal is a Secret Portal of its own, with a chance to drop when you clear all 50 waves of Summer Hunt. Explosion Mage is the final boss inside, and the creators who cleared it got the unit. One creator found that in one run, Aqua units got a buff from that portal’s modifiers. More on the unit is on our Explosion Mage page.

Summer Hunt also has secret drop cards, and sources split on what they boost. One side says Secret Portal odds; the other says charm odds. We have seen nothing that settles it, so treat either boost as unproven.

The community wiki, last edited in March 2025 before UPD 21, lists older portals such as the Puppet, Eclipse and Noble Portals as Infinite Mode drops. We have not checked whether any of them still drop in UPD 21.

Sky Portal tiers

The event quests name three tiers: Tier 9 for Sea of Clouds, Tier 10 for Above the Clouds and Tier 12 for Heaven’s Gate. So the quests go up to Tier 12, but we have not confirmed that 12 is the top tier.

The creators we compared agree that higher tiers add lanes, up to two or three paths, and are harder but pay more. Every portal also carries buff or debuff modifiers. We have not confirmed which tier first adds a path, or the full modifier list.

How to run a Sky Portal

The inventory has a Portals tab, and that is where your Sky Portals wait. Across the creator videos we watched, each run is 20 waves on Sky Island and a portal is used up once you play it. We have not confirmed whether a lost run keeps it.

The portal panel, as read on screen in more than one video, gives joiners a 25% chance at each reward the host gets. As read from the event text in videos, each extra party member adds 5% SummerPearls, up to 25%, in Summer Hunt and Sky Portals. By our read, hosting a full party gets you both.

Creators running these portals met Soaring enemies here too, and only units on Hill spots can hit them, so bring a Hill unit. Which units reach them is on our anime adventures enemy types page.

Charms and secret drop chance

Creators covering the event agree that a charm can raise your secret drop chance in both Summer Hunt and Sky Portals, and that summer units and skins add their own Secret Portal rate boost. Where charms drop and what else they roll is under summer charms on the event page. The odds of a Sky God’s Portal, the Sky God drop rate and any pity system are unpublished, and no one has measured them, so we cannot say how much any boost adds.

Sky Portal rewards

The Summer 2026 banner lists Portals as a source of SummerPearls, beside Summer Hunt waves. A clear also gives Star Remnants, as several videos show. Each count comes from one video: a Tier 4 panel listing 1 Star Remnant, and a Tier 10 panel listing 5 for the host.

Star Remnants also feed trait rerolls in place of a Trait Reroll Token: one per reroll on a low-rarity unit, and creators report five on a Mythic or Secret. A clear can also give a Sky God’s Portal, the route covered above.

Sky Portal quests

The Event tab of the quest menu listed seven Sky Portal quests on November 3, 2026.

Quest	Goal	Whose room	Reward
Sky Island	1 clear, any tier	Anyone’s	2
Sky Island II	10 clears, any tier	Anyone’s	7
Sky Island III	30 clears, any tier	Anyone’s	13
Above the Clouds	Tier 10 or above, 5 clears	Anyone’s	7
Sea of Clouds	Tier 9 or above, 1 clear	Yours, as host	8
Heaven’s Gate	Tier 12, 1 clear	Anyone’s	15
Sky God	Sky God’s Portal, 1 clear	Yours, as host	12

Each number is paid in an item drawn with the same crystal blade as a Trait Reroll Token; the panel never names it, and a second figure beside it runs off the edge. Joined runs count for quests marked Anyone’s. Other event tasks are in the full summer quest list.

Units for Sky Portals

Where the Sky Portal units sit on our list

• S Sky God Damage Creator videos place it in the Sky God's Portal, a chance drop from Sky Portals. Three of the four tiers it was given are S.
• S Explosion Mage Damage An explosion you aim, about every 20 seconds at max, but it cannot hit Soaring enemies. All four tiers given are S.
• A Water Goddess Support Hill unit that can hit Soaring enemies and gives units in range +50% water damage.

Tiers and notes from our ranking: Anime Adventures Tier List

The box above shows where these units sit on our list. In the creator videos we watched, Water Goddess is a Hill unit that can hit Soaring enemies and gives units in range +50% water damage, so on paper it fits here. Explosion Mage is the opposite: its aimed blast cannot hit Soaring enemies, so it needs a Hill unit beside it. Sky God is the Secret tied to these portals, through the route above; its kit, its Soaring blind spot and the partners players pick are on our Sky God page. Other units are on the anime adventures tier list.
