OSRS TCG Tanzanite mutagen — frequently asked
- How rare is the Tanzanite mutagen card in the OSRS TCG?
- Tanzanite mutagen is a Rare card. Packs in the TCG plugin land on a Rare card about 16% 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 Tanzanite mutagen card worth?
- The in-game item is worth 9 500 gp, which gives the card an OSRS TCG score of 9,500 and puts it in the Rare tier. What it is worth to trade is whatever another player will give for it.
- How do I get the OSRS TCG Tanzanite mutagen 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 Tanzanite mutagen, and anyone holding one can make you an offer.
- Can I trade the Tanzanite mutagen 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.
