Can You Beat Genshin Impact Using Only Dehya?!

Over 2 years ago, Genshin Impact 3.0 was released, which gave us the brand-new nation of Sumeru. Sumeru came with 2 brand new archon quests, and in those quests were a bunch of brand-new characters that would soon become beloved. One of those characters was Dehya, who was also a popular character that people couldn't wait to become playable. Despite this, it took her OVER 6 MONTHS TO RELEASE! But then the time finally came in version 3.5, where she was finally getting released. What was the general consensus on her gameplay after her release? People fucking hated it. People didn't like how she didn't really excel in any field, especially when she released. In my opinion, that's fine because she's a standard 5-star. Currently no standard 5-star character is even near the top of the meta, So I still, after all this time, don't understand why people get so upset over Dehya being just alright. To try and prove that she's perfectly acceptable, I'm going to try and beat the game with only her. Rules: I can only use Dehya in battle. Any puzzles that require another element can be completed with another character. No healing items in battle. No fighting enemies in co-op. All claymores are allowed.
