Gridmaster Reveals 10/14
A spooky new image has been added to row 1, column 6. Edit: Commenters say it means Yama.
Row 7, column 3 is now: > Deposit a Skillcape into your Player Owned House
> *Spikey Aura*: You reflect at least 25% of damage received. This effect stacks with other recoil effects.
The reward for completing row 5 also has a GIF now: https://cdn.runescape.com/assets/img/external/oldschool/tsk/reward-E.gif. Haven't been able to catch what the image is, but I'm sure someone will. Edit: It's a troll.
