Multisong Penalty

[Tgo01]

Does anyone know the formula for reducing the multi song penalty?

If so, please share.

If not, let's figure it out!

According to Krakiipedia it's 12 mana per song after the first song and discipline and logic bonus as well as bard spell ranks lowers this penalty.

My bard currently reduces the multi song penalty by (39 according to officials, 51 according to KP) mana with a 10 discipline bonus, 21 logic bonus and 30 bard spell ranks.

From this the easiest formula I can gather is bard spell ranks -4, + discipline bonus + logic bonus.

Can anyone else share their stats and how much they reduce their multisong penalty by? Or just give me the formula if it's known?

Yeah, KP is wrong and the formula is unknown as far as I know. I made a thread a while ago and there were some posts with data.

I summarized the data in one of the posts. I haven't played my bard except to purify so I haven't collect any more data points. EG digging and other purchases have bogged down some of my characters. But, there is some data there and the contribution from training in bard base was determined but that's it. I don't have anything else to contribute at the moment. Maybe I'll take another look and see if I have anything to add.

Reading all of that made my brain hurt.

Do we at least know if logic and discipline bonus help at all? What exactly do we know KP is wrong about? Does the multisong penalty kick in on the second song or third song? KP and the officials apparently say different things in regards to this and I know the official website isn't immune to being wrong.
