OSRS TCG Sir Jerro — frequently asked
- How rare is the Sir Jerro card in the OSRS TCG?
- Sir Jerro is a Uncommon card. Packs in the TCG plugin land on a Uncommon card about 32% 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 are the Sir Jerro card's stats?
- The card carries the monster's own numbers: a combat level of 62, an attack style of Slash and a max hit of 8. The OSRS TCG scores monster cards at 1.5× their level squared, which is why a high-level boss outranks most items.
- How do I get the OSRS TCG Sir Jerro 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 Sir Jerro, and anyone holding one can make you an offer.
- Can I trade the Sir Jerro 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.
