Is LEGO The Skull Arena retired?
Yes — The Skull Arena (21145-1) has been retired by LEGO and is no longer in production. Retired sets have fixed supply, which is why their prices are driven purely by the resale market.
Has LEGO The Skull Arena gone up in value?

What is the price per piece for The Skull Arena?
At its $20 retail price across 198 pieces, The Skull Arena works out to about $0.101 per piece. Collectors often use price per piece to judge whether a set is good value.
Is LEGO The Skull Arena a good investment?
The Skull Arena currently trades 110.1% above its $20 retail price, and it is retired, so no new supply is entering the market. Past performance is not a prediction — condition, packaging and how long you hold all affect what a set actually sells for. BrickStats reports the numbers rather than giving investment advice.
Why is LEGO The Skull Arena so expensive?
The Skull Arena was released in 2018 and has since retired. Once LEGO stops producing a set, the only supply is what is already in circulation, so sealed copies in good condition compete for a shrinking pool of stock. That scarcity, not the parts, is what moves the price.
