Looking at Mobs in The One Probe

When your crosshair lands on a living entity, the tooltip switches to an entity readout.

• Entity name - the name of the mob or animal you are aiming at.
• Source mod - which mod the entity comes from, handy for identifying creatures from content mods.
• Health bar - a live bar showing the target's current and maximum hearts, so you know exactly how much damage it has left before it dies.
• The readout updates continuously, so you can watch a mob's health drop in real time as you fight it.
