Thanks for your reply.
If you check the Battle Core of VisuStella there is an option for casting/attack animations that can be set to 0 (no animation).

Also if you do wish to change the Poison state, try this:

One thing to be aware of the above I think it applies to MP (TP) as well as HP, so you may be hesitant to change that.
As for the intro, I'd be happy to try get one sorted for the game. Please give me a week or two and I can show you what I made.
One last thing: I encountered a bug when I entered Techna Castle stairs to below ground in the Ayn scenario, that put me back to one of the dome connecting tunnels? Very stupidly, I then saved the game before I realized I could not get back to Techna because Lyle takes you, meaning I could not get over to Techna from the Lensol side again!!!! Ah... oh well, I'll just play a different scenario from the beginning.
Again thanks for making this, I want this to be the version of PSIII I return to time and again since the gameplay in this is so much better than the original. I'll be in touch soon, bye for now :)
