Claire is an SSR Warrior from the F2P core squad (F2P start, part 2) and she can now become a UR hero. This is called ascension: the rarity changes to UR, the skills get advanced versions, and the stat growth per level and star becomes about 1.5 times higher.

What you need
- Claire at 10★ (the condition in the ascension window: "Hero Claire has reached 10★").
- The item Claire's Advanced Mark, which is used in the event interface to upgrade Claire to UR. The Mark is given in the season for reaching 100 Virus Resistance; at the next Resistance thresholds (from 200 to 9000) you also get Claire Shards - 320 in total.
The ascension is confirmed in the "Notice" window: the hero's development cost changes after it, and the details are behind the button in the top right corner.

What resets and what comes back
| after ascension | |

| Skill Badges invested in Claire | returned by mail |
| shards invested in the Hall of Honor | returned by mail |
| shards spent on stars 0→10★ | not returned |
Skills: SSR vs UR
The base skill damage at the same level is the same, but the star effects of the advanced skills are noticeably stronger. The star thresholds are the same.
| skill (SSR → UR) | star | SSR | UR |
|---|---|---|---|
| Holy Banner → Adv. Holy Banner (auto attack) | 1★ / 5★ / 10★ | +25% / up to 60% / up to 120% damage | +40% / up to 100% / up to 200% |
| Celestial Judgment → Adv. Celestial Judgment (ultimate) | 2★ | damage to monsters +8% for 7 sec. | +10% for 7 sec. |
| 6★ / 10★ | +35% / up to 95% damage | +100% / up to 200% | |
| Rain of Arrows → Adv. Rain of Arrows (active) | 3★ / 7★ / 9★ | +25% / up to 60% / up to 120% | +50% / up to 130% / up to 240% |
| Call of the Brave → Adv. Call of the Brave (passive) | 4★ / 9★ / 10★ | +1.6% / +2.4% / +4% | +2% / +4% / +8% |
| Tenacity → Adv. Tenacity (support) | lvl 30 and 8★ | ATK, HP, DEF +10% | +20%, Skill Cooldown Speed +10% |
Call of the Brave still boosts damage to monsters for the 3 Warriors with the highest attack in the squad - and the whole F2P core squad is Warriors.

Right after ascension the skills are at level 1 and can only be raised to level 10: beyond that the skill level depends on the hero's stars (levels 11-15 need 7★, 16-20 need 8★, 21-25 need 9★, higher needs 10★). Upgrading costs Skill Badges, and the prices per level are the same as for SSR.
Stars after ascension
The stars of UR Claire are raised with her Shards or SSR Hero Omni Shards, but you need twice as many shards as usual.

| stars | SSR, shards | UR, shards |
|---|---|---|
| 6★ → 7★ | 125 | 250 |
| 7★ → 8★ | 175 | 350 |
| 8★ → 9★ | 200 | 400 |
| 9★ → 10★ | 300 | 600 |
| 6★ → 10★ | 800 | 1600 |
For comparison: the SSR Claire path from 0 to 10★ cost 975 shards, and they do not come back on ascension. Getting back to 10★ as a UR hero takes another 1600.
