• Casting a Circle spell is always obvious. The components of a spell cast as a Circle spell cannot be modified (such as through Subtle spell) except as noted in Circle Casting Options.
• Each secondary caster must maintain concentration on the spell being cast until the spell casting is completed regardless of the casting time. Breaking concentration causes the spell to fail as normal. 

The Rabbit Hop ability allows for multiple jumps as part of the bonus action, but the normal jumping limitations restrictions apply to each jump.

Per the ruling on Disciple of Life, a Moon-Sickle will increase the healing of each berry in a Goodberry casting.

• Secondary casters are determined when initiating casting the Circle spell.
• Each secondary caster is caster of the spell and a valid target for effects that target a creature casting a spell. In the case of Counterspell, the components of the spell being cast determine if the secondary casters are targetable (because of the house rule above, secondary casters are always targetable).
• Failing to contribute to a spell causes the spell to fail.

Player companions follow the same rules as Players when reduced to 0 HP unless the companion has explicit rules otherwise; they are not automatically dead at 0 HP.
