As for my efforts, The Arena of Khaboom has its moments as does Strangebrew, while Wizard Went a-Wooing caters for L13 wizards.
Here's my suggestion...
- Saving rolls: either a) follow 5.5 and make 1,3 a failure as well as 1,3 or b) raise all INT, LK and DEX SRs so that you need a minimum of 6 to make the roll e.g. your INT is 54 so you need a L9 SR for success (you can imagine a tougher situation to fit the level of the SR).
- For MRs, roll 1d6 then:
- 1 or 2 - start with a MR that gives 50% of your combat adds (e.g. your CAs = 100 so base MR is 100) then add 2d6 DARO x 10
- 3,4 or 5 - start with 75% (e.g. with CAs = 100 the base MR is 150)
- 6 - start with 100%
There - that might give you more of a challenge!
