You are able to hold the charge for one touch spell per arm of your body as long as you don't use a charged limb to cast another spell or touch anything with it. Each touch spell you cast resides in a different forelimb. For the duration of this spell, any touch spells you cast are discharged only if you cast another spell with that forelimb or touch something with that forelimb. If the spell flower effect ends, the most recent touch spell cast remains as a held charge and all other held spells dissipate.
