Barbarian versus Rogue
Krunch the Barbarian thinks he has gone as far with his barbarianism as he can, and chooses to train more as a Rogue from now on. He's quite excited by the opportunities this will allow. 'I can be stealthy now, if I want to be.'
Pigeonhole, our actual Rogue, is happy to offer some advice. 'What armour do you have?'
'Hmm, half plate. I may need to change that.'
'No, keep it.'
'But we have the potential to be all stealthy!'
'Yes, that's why you should keep the armour.'
'But wouldn't I be heard?'
'Making you the main target. Sounds perfect.'
