Tactics

The Titan emerges from beneath the earth to control terrain and surprise foes. It favors multi-target attacks, collapsing tunnels, and environmental hazards to funnel enemies. It uses Tremorsense to detect hidden or burrowing creatures. Its actions are instinctive and territorial, not malicious; it fights to defend its domain and maintain balance.

• Frequent minor earthquakes and tremors occur.
• Volcanic and geothermal activity increases.
• Subterranean tunnels and caves may collapse unpredictably.
• Surface vegetation near its lair often wilts due to heat and vibration.

Chthonian Titan

You see a colossal humanoid, if this hecatomb thing could be said to be related to humanity in any way. Its arms are as towers, its legs as mounds; its chest is a furnace and its head is like a world full of chaos and destruction.

Chthonian titans are not made of normal, or even extraplanar flesh and bone; their essence is that of inchoate pandemonium, of the primal hyper-material mud from which the universe was moulded. They appear as raging Colossal humanoids with varying monstrous features, such as an uneven number of eyes or limbs; fire coming out of their eyes, mouths or hair; gigantic claws and so on. Their skin is usually some dreary shade of red, brown or black.

Chthonian titans speak Abyssal.

Combat

No two chthonian titans are alike, so they all have different attack methods. As a rule, they prefer to use their godlike chthonian traits rather than normal melee attacks or spelllike abilities.

Chthonian Traits (Ex): Chthonian titans are creatures of chaos, and as such their physical features are jumbled and confusing. These diverse physical features are usually accompanied by unique special abilities, which no two chthonian titans share.

Every chthonian titan has 1d3 of the following traits, chosen or randomly determined from the table below. These traits are just examples; a Games Master may come up with different chthonian traits as he sees fit.

Chthonian Traits
D100 Roll	Trait	Explanation
01-05	Breath weapon	The chthonian titan may breathe a cone of acid, cold, fire, electrical, negative energy or poison (choose one) dealing 18d6 damage; a Reflex save (DC equal to 10 + half the chthonian titan’s Hit Dice + the chthonian titan’s, Constitution modifier) is allowed for half damage
06-08	Chaotic mind	The chthonian titan gains a +4 racial bonus on Will saves, plus any creature using a Divination spell targeted on the chthonian titan must in turn succeed at a Will save (DC equal to 10 + half the chthonian titan’s Hit Dice + the chthonian titan’s Wisdom modifier) or become confused (as the spell) for one full minute
09-14	Claws	Substitute slam damage for 4d6 claw damage
15-20	Curved horns	The chthonian titan gains a secondary gore attack, which deals 4d6 damage plus one-and-a-half its Strength modifier
21-23	Digging claws	Substitute slam damage for claw damage; the chthonian titan gains a burrow speed equal to half its base movement speed

00	–	Roll twice, with each 00 counting as an additional roll (do not reroll double 00’s)

Epic Spell-Like Seeds: Chthonian titans have access to the destroy and energy epic spell seeds, just as if they were spell-like abilities. They may develop a different effect every time they use one of these seeds. Using an epic spell speed is a full-round action for a chthonian titan. A chthonian titan requires no Spellcraft check to use or develop epic spell effects based on these seeds.
