Where the DM is seeking money for re-roll monsters attacks, having them dodge fatal blows, or even resurrecting after falling in battle, myself and my fellow adventurers have the following options:
£1 to re-roll a single dice
£3 to start with an extra piece of rare equipment
£5 to stand up after a fatal wound, though only with 1 hit point
£10 to cheat death entirely and stand up on full hit points
If you would like to aid my character, the charismatic Gnome Rogue Scholar "Indiana Gnomes" see the adventure through to the end, please donate to his war chest.
But if you would prefer to see our pint sized heroes put through the ringer, you can instead donate to the DMs war chest at https://www.justgiving.com/fundraising/mik-calow-dm
But either way your alignment falls and you donate, it all goes to the same good cause in honour of friends and family of the participants who have battled with Dementia.
