A new system is in place for group-selected units that allows better control of battles involving multiple unit types. When you select different types of units together in a group, the units automatically subgroup by unit type. You can then select subgroups within the group and use their special abilities without having to deselect the group. If you're controlling a group comprising these subgroups, one of the subgroups is always highlighted (indicated by the current portrait model and the size and highlight of the units in the info card). The special abilities particular to the highlighted subgroup-such as spells, inventory, etc.-are available in the command card (in addition to the basic orders such as Move and Attack, which the entire group will follow regardless of which subgroup is highlighted).

• Subgroups are sorted in the info card by priority, with the highest priority units being placed first and lowest priority units being placed last.
• Pressing TAB highlights the next subgroup within the group.
• Pressing SHIFT-TAB highlights the previous subgroup within the group.
• You can also select a subgroup by left-clicking on an individual unit in the group, and you can select an individual unit by left-clicking it in the highlighted subgroup.
• Heroes are separated into their own subgroups regardless of whether there is another Hero of the same type in the overall group.
• If you give a subgroup containing multiple casters the command to cast a spell, only one caster will cast the spell. This prevents spells from being wasted. It also frees you to select the spell and the target each time without having to select the individual caster in the subgroup to cast the spell.
• You can cast spells on units in subgroups by selecting a spell and left-clicking on a unit in the info card.
