OSRS TCG Crystal weapon seed — frequently asked
- How rare is the Crystal weapon seed card in the OSRS TCG?
- Crystal weapon seed is a Common card. Packs in the TCG plugin land on a Common card about 37.34% of the time. Rarity is not assigned by hand: the OSRS TCG plugin scores every card from the in-game item's value, or from a monster's combat level, and its tiers are percentile bands within a card's own group — items are ranked against items and monsters against monsters, because a boss's level and an item's price are not the same measure.
- What is the Crystal weapon seed card worth?
- The in-game item is worth 1 gp, and under the OSRS TCG's rarity rules items worth 0 or 1 gp are pinned to Common rather than being ranked — otherwise the cheapest items in the game would sort against each other for a rarity they never earned. The card's trade value here is whatever another player will swap for it.
- How do I get the OSRS TCG Crystal weapon seed card?
- Open packs in the OSRS TCG RuneLite plugin and hope for the pull, or trade for it. A Standard Pack costs 2,500 credits — earned by playing Old School RuneScape — and reveals 5 cards, each with a 1% chance by default of coming out foil. On OSRS Card Exchange you can post an exchange offering a card you have spare and asking for Crystal weapon seed, and anyone holding one can make you an offer.
- Can I trade the Crystal weapon seed card with another player?
- Yes. This site matches the two of you and hands over a party passphrase; the cards themselves change hands in the TCG plugin's own Trade window in game, not on the website and not through the standard in-game trade screen.
