Heart of Tarrasque is a purchase with a specific job. This guide explains its effect, the situations where we would consider it, and the limits that matter before you spend your gold. Prices and recipe totals use the dated Valve snapshot shown below.

Choose a concrete job: stand in front of a tower push, absorb an opening spell sequence, or recover between exchanges. Health with no useful job can be an expensive detour.
Healing and regeneration reduction can weaken a sustain plan. Look at the enemy items and abilities, then compare whether armor or another defensive effect would solve the immediate threat better.
Back off when necessary and let regeneration contribute before returning. Staying at low health in front of every enemy is not required to benefit from a missing-health mechanic.

The same health pool lasts differently against different damage sources. Our advice is to consider your existing armor and spell defenses before spending heavily on regeneration.

Valve states that multiple Behemoth’s Blood passives do not stack. Use your limited inventory slots for complementary effects rather than expecting doubled regeneration from that passive.

Walk forward when allies can use the space you create. If everyone is elsewhere, an isolated tank can still be controlled and killed without gaining an objective.

No. It increases durability and sustain, but it does not prevent disables, remove debuffs or guarantee that regeneration outpaces enemy damage. Your other defenses and positioning still matter.
