I just need to actually cast the spell... I mean a botch could be fun!
As close to the River Ness as they can get, Talia prepares her ritual for changing the shape of the ship to have a flatter bottom. "Captain, I'll be relieving you until we make passage to the loch, and the spell has expired. After that, we'll continue on to the covenant. Once I'm docked, you can take the rigging, sails and anchor and equip the other ship in the sheltered cove my men have beached her."
She'll then prepare for the Ceremonial casting to lift the ship a few feet higher, to avoid running aground.
The level is 25, as discussed elsewhere, and also for the Hull of Unbreakable Iron need to have a size +3 component. Base 3: R:Touch, D:Sun, T:Ind Size+3 is a total level of 25. Talia's Casting Score in 1224 is Rego 6 + Herbam 10 +Sta 2 + Artes Liberales 2 + Focus 6 +20 Vis (using 10 pawns of Herbam, as before) =46.
And the die roll is... a 1, (Woot!) followed by a 7. For a total of 60/2=30.
I'll update Talia's Herbam vis accordingly.
She'll comment to no one in particular, "I don't know why more magi don't use vis to power their spells. It makes it so much easier."
She'll direct the crew to make their way upriver, and will use any of her formulaics as necessary to complete the journey. Wonder if Aodhan will comment on her "wasting" of vis...
