Too many dwarves with SWORDS, not enough dwarves with AXES. You can go ahead and think a Dwarf with an Axe or a Hammer is cliche but literally ANYTHING with a sword is worse.
There are four types of gnomes, each one opens gradually. The gnome with a hammer opens at 6th level, which is not available in the current version. The full version of the game will be released in 3-4 weeks.
