Attack 1: Tail Swipe
Bash's mace tail is his strongest feature. This powerful swipe inflicts massive damage; only some of the Giants inflict as much damage right out the gate. It's so good, that the Granite Dragon Path isn't really even necessary. If you do choose the Granite Dragon Path, Gaia Hammer is one of the highest-damage attacks in the game. It can dish out over 200 damage! The charge takes a moment, but against bosses, it should be your primary attack.Attack 2: Rock and Roll
For a dash-type attack, Rock and Roll dishes out serious damage. While it's not as fast as other dash attacks, the extra damage more than makes up for it. The end result after buying all the upgrades is a dash-type attack that does more damage than the base mace tail attack, has excellent range (Bash turns into a giant ball once he gets Continental Boulder), and dramatically increases Bash's defense.
Attack 3: Summoning Stone Projection
Stone Projection is an interesting power that gives Bash some range. It does a high amount of damage whether you use the projection as a mid-range area-of-effect attack, or smash the stone to launch a ranged stone. One difficulty of Stone Projection is that it's difficult to aim the ranged attack. It's long range, but it doesn't have much utility since it's so hard to aim correctly.
Wow Pow Power: Rolling Thunder!
When you activate this ability, Bash uses his stone projection to create a ramp, and moments later he slams into the ground with a very wide-range area-of-effect attack. Enemies caught directly in the blast take a lot of damage (approximately double a normal roll attack).
Soul Gem Ability: Triceratops Honor Guard
One of Bash's weaknesses is his low armor. When you purchase this ability, Bash's base Armor stat goes from 12 to 52! That's a huge improvement and lets him hang in tough close-range combat situations longer.
