Classic Version — Order of the Sword

ilovejello

Going thru quests again, I am the order of the sword castle, and I can’t remember how to get into the treasury.
I’m in the correct hallway, I don’t remember the loc and spell to activate it.

Catacomber

There's no spell. Just tap the nice painting on the east wall, to the east of the painting of Stepan of Horalek. Same in the HD version.

The paintings are all on east wall. I thought I remembered walking from either the green wall or the black wall and casting a spell. Is there a certain level? I’ve tapped on everything.

Catacomber

It normally says, 'A nice picture isn't it.' But if you tap it enough times, the wall will disappear. It's scripted to happen if randomness is greater than 90. So, keep tapping.

This is the script:
if((evtuse()) && (random(100)>90)){
tain_marttreasury.sethidden();
tain_marttreasury2.sethidden();
player.addcrime(50);
player.addxp("10000");
tain_martdrag1.setvisible();
tain_martdrag2.setvisible();
tain_martbrick22.setvisible();
tain_martbrick42.setvisible();
message("You have just managed to get yourself into Martelius' treasury... and a BIG trouble too.");
} else {
message("A nice picture, isn't it.");
}
