An inhibit TP spell would be nice. It could be a long lasting weak effect but I'd prefer a moderately long recast(60 seconds) with a huge potency and declining effect similar to Flash. It could be a 100% TP inhibit for a few seconds and decline over time. The inhibit could also counter Regain effects comparable to the effect % at the time. So after it's worn to 50% TP inhibit after a few sec it inhibits 50% of their autoregain if they have. Another could be a plague which DoTs their MP/TP which could be sweet. The MP part is meh since mobs have THOUSANDS of MP, but the TP decay would be great!
