I hit day 160 and got the message about the Tower being overrun with demons. The walkthrough said that it would be suicide to go into the Tower without Repel Spirit level 3, but it also said that I needed to fix the tower right now. Well I only had Repel Spirit level 2 but I thought I'd give it a go. I fought my way through all the demons and tried to get through the secret passage in Linda's room only to find Linda's room wouldn't open! I tried bashing it and Unlock Door, but I guess it needs higher than Level 2 which is all I had. So I figured I now had to get to the portal the hard way by fighting through the Hakis. I fought through the Hakis and destroyed the portal but I only had one character left. I figured I'd get my characters resurrected and go back and collect my stuff, but of course the tower collapsed and now my stuff is all gone. Diamond Dagger, Steel Plate Mail, Mithril Chainmail, Serendipity Knife etc etc. This victory was a bit to pyrrhic for my liking.
So I went back to an earlier save of day 159 and went up to the House on the Hill to read the Unlock Doors level 3, crossing my fingers that that would be enough to open Linda's room. Well I got Unlock Doors 3 and it's day 159 and I'm about to get the message about the tower, is there anywhere I can get Repel Spirit level 3 on the way there?
