My understanding is that you are posting how DT used to work. It used to give +1000 armor for 30 seconds. However, NOW it instead gives complete invulnerability to all physical attacks for 30 seconds. Your example with the shadow dragon was before the change. If you tried it now, and if the Shadow dragon's kill ability counts as physical damage, you should take no damage. The current version of DT is really much stronger than the version you used against the Shadow DRagon.
