A Seeker is a misting who can burn bronze. If they become an Inquisitor, they gain the ability to pierce copperclouds as they receive more power from the hemalurgic bronze spike placed in them upon creation. *This applies to all bronze hemalurgy spikes used on a seeker (i.e. Vin)
Seeker Mechanics
When burning bronze , either Misting or Mistborn, the user can feel the uses of allomancy near them. The manner in which they feel the signals is often described as like a drum beat (formally known as an allomantic pulse). A thumping that is less heard, but felt. The signals can tell you where the burner is, or the pulse origin, and can distingiush between metals.
When burning bronze the pulses come in specific patterns depending on the metal being used. Pushing and pulling metals are distinguishable because the pulses of Pushing metals wash over the Seeker, while Pulling metals tug them towards the source ever so slightly. This is where some of the metals actually aquired their titles, such as tin and pewter. The Internal and External metals are seperated by their pulse length. Internal metals give off longer pulses than External metals. The different metal groups, physical, mental, enchantment and temporal have distinct pulse patterns, fluxuation in speed and tempo. Pinning down these three attributes can identify what metal the Misting or Mistborn is using. It is also stated that a powerful and skilled Seeker can identify when an allomancer is flaring metals, running low and what emotions a Soother or Rioter is trying to affect.
Copper neutralizes the ability for a Seeker to track allomancy by hiding it in a copper cloud, but extremely powerful Seekers or Mistborn, from either a pure line of heredity, bronze used in tandem with duralumin, or a bronze hemalurgic spike may give the affected allomancer the ability to pierce copper clouds.
